Sciatica is a neurological condition that mainly arises due to problems in the sciatic nerve. The sciatic nerve is believed to be the largest nerve originating from the spinal nerves L4 to S3. It extends downward from the lower spine into the back of each leg (thighs) right down to the foot. The sciatic nerve acts as a connecting link between the spinal cord and the foot and the leg muscles. People with sciatica often experience a tingling sensation along with a shooting pain radiates downwards from the lower back (mostly the lumbar region) to the back of one of the legs. Some may also experience the sciatic pain down both the legs (rare).

Types of Sciatic Pain:

Sciatica that affects a person can be of two types depending on the severity of the associated symptoms

Acute sciatic pain: In this case, a person experiences a sudden radiating pain which often heals by itself within a week or two. More than often, the pain is triggered by an injury to the spinal joints, nerves, or the disc.
Chronic sciatic pain: This is a more serious condition where the pain may linger for long, often more than three months. The chronic sciatic pain may affect a person with severe Arthritis and nerve injury and damage.
Symptoms associated with Sciatica:

One of the characteristic symptoms of Sciatica is a shooting pain that radiates from the lower back (often the lumbar) to the back of one (or both) of the legs.
In some, the sciatic pain may result in weakness and a tingling sensation down the affected leg.
A person with sciatica may find it difficult to move his/her foot and legs (restricts their movement).
Some people may experience a shooting pain even while they are in a sitting position. In some others, the pain may be at its worst when a person is in a standing position.
Sciatica can also trigger a hip pain.
What triggers sciatica and the associated symptoms?

The disc is a protective shield that prevents any damage or injury to the vertebrae. A degenerative disc problem can interfere with the normal functioning of the disc triggering sciatica.
Spondylolisthesis: In Spondylolisthesis, also known as a Slip Disc, a bone (mostly in the lumbar region) slips over the bone which is located just below it. People with prolonged and untreated spondylolisthesis are often known to suffer from sciatica.
The sciatic pain can also affect a woman during her pregnancy.
Lumbar spinal stenosis: This condition is is characterized by the spinal canal narrowing down in the lumbar region. Lumbar spinal stenosis exerts pressure on the sciatic nerve, giving rise to sciatica.
A muscular strain or spasm in the buttocks can also be a contributing factor.
Proper management and prevention for sciatica are possible. One should be alert and consult a doctor in case they experience the associated symptoms or any discomfort.

Sciatica Pain - What Can Trigger It?

Sciatica refers to the pain one experiences due to the irritation or compression of nerve roots contributing to formation of Sciatic nerve. The sciatic nerve is the longest and widest nerve in the body, running from the lower back, down to the back of each leg. The pain can occur in the lower back and spread to the hips, buttocks and leg. Sciatica generally affects one side of the body. There are numerous causes of irritation of the sciatic nerve and sciatica.
 
Some of them are:
 
1. Spinal Stenosis
The narrowing of the spinal canal caused by natural wear and tear of the vertebrae (individual bones in the spine protecting underlying nerves) of the spine is known as spinal stenosis. The narrowing may put pressure on the roots of the sciatic nerve, causing pain.
 
2. Herniated Disc
A disc is made up of cartilage and acts as a cushion between vertebrae, allowing flexibility of the spine. A herniated or slipped disc occurs when a disc is temporarily pushed out of place, putting pressure on the sciatic nerve.
 
3. Spondylolisthesis
It is a condition where one of the lower vertebrae slips forward over another. This also causes a collapse of the disc space between both, causing the nerve to get pinched. This may cause sciatica.
 
4. Piriformis Syndrome
Piriformis is a muscle found deep inside the buttocks, which connects the lower spine to the upper thighbone, running directly over the sciatic nerve. Spasming of this muscle can pressurize the sciatic nerve, triggering symptoms of sciatica.

5. Sacroilitis
Sacroillac joints are the place where the lower spine meets the pelvis and inflammation of one or both of these joints causes sacroilitis. This can give rise to symptoms of sciatica as it causes pain in the lower back, buttocks and legs.
 
6. Spinal tumors
Very rarely, tumors growing inside or along the spine may put pressure on the sciatic nerve.
 
7. Infection or injury
Muscle inflammation, infections, fractures or any other spinal injury may lead to irritation or compression of the sciatic nerve.
 
8. Pregnancy
Pregnant women may suffer from sciatica due to weight gain, expansion of the uterus or increased fluid retention or other changes occurring in the body, which put pressure on the sciatic nerve.
 
9. Other causes
Osteoarthritis and fractures caused by osteoporosis may also affect the sciatic nerve, producing symptoms of sciatica.

Top 9 Causes Of Sciatica Nerve Pain - You Need To Know About

Sciatica is probably one of those things which is vaguely familiar but a person is not fully aware of it. The sciatic nerve is one which is part of the spine and then spreads out over the legs. When this nerve gets pinched, it leads to sciatica, or pain of the sciatic nerve, which is tremendous! But, then, what exactly is a person to do in order to reduce the pain caused on account of sciatica?


The best answer for this is not medication, though it does have its uses, but rather, exercises which help the situation improve and reduce the risk of the person going mad due to the pain! One of the simplest exercises that a person can start with is known quite commonly as the knee to shoulder exercise. All that one needs to do is to lie down on the back and then, raise one knee and pull it across the body, with hands wrapped around it, so that it touches the opposite shoulder. This position of the knee touching the shoulder is to be held for about half a minute. About 3 repetitions need to be done and the same with the other side.


While it is important in the effort to relieve pain due to sciatica, it is equally important not to push oneself beyond natural limits, especially initially as this can cause injury. After all, more pain is the last thing which a person with sciatica is likely to want!


Since it is important to keep in mind the fact that consistency is one of the key secrets to reducing the sciatic pain, it is worth keeping in mind the standing hamstring stretch. What this exercise can boast of is the fact that it is one which can be done nearly anywhere. Also, it is pretty simple, too!


To do the standing hamstring stretch, one leg needs to be kept on an elevated surface which is not as high as the level of the hip. It is important to keep in mind that the leg is to be kept straight. The torso needs to then be bent towards the elevated leg. This process should be done slowly and again, maintained for about half a minute.


The sitting pose is useful to remember, as well. Sitting on the floor, one leg s ankle should rest on the other s knee. Like the standing hamstring stretch, the upper torso is to be bent towards the extended leg. With all these exercises, relief is not far away!


Top Ways To Get Pain Relief From Sciatica

The sciatic nerve spreads down the spine till the legs. The pain in this nerve can feel like sparks running down your leg (by and large only each one in turn) or cause pain in the lower back. Anything that puts weight on or aggravates this nerve can cause pain that shoots down the back of one butt cheek or thigh. The amount of pain can increase gradually. Sciatica may feel like a gentle ache, a sharp sensation or extreme uneasiness. Sciatica can bring feelings of shivering, numbness and weakness.

Sitting, standing up, coughing, sneezing, lifting, or straining for a very long time, might aggravate pain. Now and then, individuals experience numbness or shivering in the leg, too. Some of the most regular symptoms of sciatic pain include:

1. Lower back pain
2. Pain in the back or leg when sitting
3. Hip pain
4. Burning sensation in the leg
5. Numbness or trouble moving the leg or foot
6. Continuous pain on one side of the back
7. Shooting pain that makes it hard to stand up properly

The most common causes of sciatic pain include:

1. Lumbar spinal stenosis (narrowing of the spinal channel in the lower back)
2. Degenerative disk sickness (breakdown of discs, which go about as pads between the vertebrae)
3. Spondylolisthesis (a condition in which one vertebra slips over another)
4. Pregnancy
5. Muscle spasms

Some of the most effective exercises for sciatic pain relief are as follows:

1. Pigeon Pose is a typical yoga posture. It attempts to open the hips. There are various types of this stretch. The first is the leaning back pigeon posture. If you are beginning your treatment, you have to attempt the leaning back posture first.

2. While on the back, raise your right leg up to a right point and hold it with both hands behind the thigh and lock your fingers. Take your left leg and touch your lower leg against the knee. Hold the position for a minute.

3. Sit on the floor with your legs stretched straight before you. At that point twist your right leg, putting your lower right leg on top of the left knee.

Bend forward and incline your abdominal area toward your thigh. Hold for 15 to 30 seconds and after that switch sides.

4. Kneel down on the floor on all fours. Get your right leg and bring it forward so that your lower leg is on the ground. Your right foot has to be ahead your right knee while your right knee stays to one side. Stretch the left leg out the distance behind you on the floor, with the top of the foot on the ground and toes pointing backwards.

5. Lie on your back with your legs facing outward and your feet flexed upward.

Wrap your hands around your knee and delicately pull your right leg over your body toward your left shoulder. Hold it there for 30 seconds and afterward push your knee so your leg comes back to its initial position.

Sciatica Pain and Ways to Deal With It

The intervertebral discs are made-up of two concentric layers, the inner gel-like Nucleus Pulposus and the outer fibrous Annulus fibrosus. As a result of advancing age, the nucleus loses fluid, volume and resiliency and the entire disc structure becomes more susceptible to trauma and compression. This condition is called as degeneration of the disc. The disc then is highly vulnerable to tears and as these occur, the inner nucleus pulposus protrudes through the fibrous layer, producing a bulge in the intervertebral disc. This condition is named as herniated disc. This can then cause compression to the spinal cord or the emerging nerve roots and lead to associated problems of Sciatica radiating pain from back to legs in the distribution of the nerve. Other symptoms could be a weakness, tingling or numbness in the areas corresponding to the affected nerve. Sometimes bladder compromise is also present, which is made evident for urine retention and this need to be taken care as an emergency.
Excessive weight, bad postures, undue movements, improper weight lifting and other kinds of traumas may weaken the intervertebral discs. When this occurs the pulpous nucleus will bulge against the annulus, or even be squeezed through it (extruded disc).

The first steps to deal with a herniated or prolapsed lumbar disc are conservative. These include rest, analgesic and anti-inflammatory medication and in some cases physical therapy. At this point, it is convenient to have some plain X-rays done, in search of some indirect evidence of the disc problem, as well as of degenerative changes on the spine.

If in a few days these measures have failed, the diagnosis has to be confirmed by means of examinations that give better detail over the troubled area, as the MRI, CT which will show the disc, the space behind it and in the first case, the nerves. In some instances, the EMG (electromyography) is also of great value, as this will show the functionality of the nerves and muscles.

Once the diagnosis has been confirmed, one of the best alternatives existing today is the Ozone Discolysis as the results obtained are excellent and practically has no complications. This novel treatment avoids the use of surgery in 80% of those who needed it. In most patients left with painkillers as the only treatment, the symptoms eventually disappear, only that this could take weeks to months. Ozone speeds up these developments, see the same result in a few weeks. The problem has to be seen and approached integrally and frequently the combination of therapies has to be used, most frequently physiotherapy. Also, it has to be known that those who had a herniated disc have 10 times more chances of having another herniation than the rest of the population.

If despite the ozone therapy the symptoms persist, Drill Discectomy/ Laser Discectomy are good alternatives before open surgery (Discectomy) which has to be contemplated in those true emergencies, as mentioned above, this is possibly the first choice.

Once the conservative treatment fails:

Early aggressive treatment plan of pain has to be implemented to prevent peripherally induced CNS changes that may intensify or prolong pain making it a complex pain syndrome. Only 5% of total LBP patients would need surgery & 20% of discal rupture or herniation would need surgery. Nonoperative treatment is sufficient in most of the patients, although patient selection is important even then.

Depending upon the diagnosis one can perform & combine properly selected percutaneous fluoroscopic guided procedures with time spacing depending upon pt`s pathology & response to treatment.

Using precision diagnostic & therapeutic blocks in chronic LBP, isolated facet joint pain in 40%, discogenic pain in 25% (95% in L4-5&L5S1), segmental dural or nerve root pain in 14% & sacroiliac joint pain in 15% of the patients. This article describes successful interventions of these common causes of LBP after conservative treatment has failed.

LESI: Lumbar Epidural Steroid Injection

Indicated in   Acute radicular pain due to irritation or inflammation.

Symptomatic herniated disc with failed conservative therapy
Acute exacerbation of discogenic pain or pain of spinal stenosis
Neoplastic infiltration of roots
Epidural fibrosis
Chronic LBP with acute radicular symptoms
Epidural- lumbar injection
ESI Treatment Plan

Compared to interlaminar approach better results are found with a transforaminal approach where drugs (steroid+ LA/saline +/- hyalase) are injected into anterior epidural space & neural foramen area where herniated disc or offending nociceptors are located. Whereas in interlaminar approach most of drug is deposited in posterior epidural space.Drugs are injected total 6-10 ml at lumbar, 3-6 ml at cervical & 20+ ml, if caudal approach is selected. Lumbar ESI is performed close to the level of radiculopathy, often using paramedian approach to target the lateral aspect of the epidural space on involved side. Cervical epidural is performed at C7-T1 level.

SNRB- Selective Nerve Root Block 

Fluoroscopically performed it is a good diagnostic & therapeutic procedure for radiculopathy pain if

There is minimal or no radiological finding.
Multilevel imaging abnormalities
Equivocal neurological examination finding or discrepancy between clinical & radiological signs
Postop patient with unexplainable or recurrent pain
Combined canal & lateral recess stenosis.
To find out the pathological dermatome for more invasive procedures, if needed
Intradiscal Procedures 

Provocative Discography - Coupled with CT

A diagnostic procedure & prognostic indicator for surgical outcome is necessary for the evaluation of patients with suspected discogenic pain, its ability to reproduce pain(even with normal radiological finding), to determine type of disc herniation /tear, finding surgical options & in assessing previously operated spines.

Percutaneous Disc Decompression (PDD)

After diagnosing the level of painful offending disc various percutaneous intradiscal procedures can be employed

Ozone Discolysis: Ozone Discectomy a revolutionary least invasive safe & effective alternative to spine surgery is the treatment of choice for prolapsed disc (PIVD) done under local anaesthesia in a daycare setting. This procedure is ideally suited for cervical & lumbar disc herniation with radiculopathy. The total cost of the procedure is much less than that of surgical discectomy. All these facts have made this procedure very popular at European countries. It is also gaining popularity in our country due to high success rate, less invasiveness, fewer chances of recurrences, remarkably fewer side effects meaning high safety profile, short hospital stay, no postoperative discomfort or morbidity and low cost.

Dekompressor: A mechanical percutaneous nucleosome cuts & drills out the disc material somewhat like morcirator debulking the disc reducing nerve compression.

Epidural Adhenolysis or Percutaneous Decompressive Neuroplasty for Epidural Fibrosis or Adhesions in Failed Back Surgery Syndrome (FBSS)

A catheter is inserted in epidural space via caudal/ interlaminar/ transforaminal approach. After epidurography testing volumetric irrigation with normal saline/ L.A./ hyalase/ steroids/ hypertonic saline in different combinations is then performed along with mechanical adenolysis with spring loaded or stellated catheters or under direct vision with epiduroscope.

Procedures That Can Help Treat Slip Disc & Sciatica!

Sciatica is a very common neuropathic pain that is caused by damage to the sciatic nerve, a large nerve that runs from the lower back region down the end of each leg. It is the largest single nerve in the body.
This condition affects around 4 out of 10 people at some point of their lives. The nature of the pain varies from a mild ache to a sharp stinging sensation and may cause feelings of numbness and extreme weakness.

Causes of sciatica
The causes for the onset of sciatica are numerous. Some of them are as follows:
-slipped lumbar disc
-muscle inflammation
-internal bleeding
-pregnancy
-obesity
-awkward sleeping position
-uncomfortable footwear
-spinal injury

How can physical therapy help?
There are many ways of treating sciatica, such as medication, acupuncture and surgery, which can provide relief. The most common and easy treatment method however is physical therapy. A progressive and controlled exercise routine that is specifically tailored to the nature of the condition in consultation with a physical therapist acts as an effective remedy in treating the problem. It alleviates pain and also eliminates the chances of relapse.

Physical therapy exercises used to treat sciatica are of many types. They are a combination of core strengthening, muscular stretching and aerobic conditioning routines, which aim at correcting the root of the problem.

The different types of exercises employed to treat sciatica include the following:
Strengthening exercises
These aim at strengthening the spinal column and the pelvic region, which includes the hips and buttocks. They help in making the muscles and ligaments in this region more robust and allow for improved flexibility and support. Lunges and squats are some of the examples.

Stretching exercises
These provide pain relief through improved agility and flexibility. The most important aspect of these routines is stretching and exercising the hamstring. Hamstring, stretches, calf stretches and tricep stretches are a part of stretching exercises.

Aerobic conditioning
These are cardiovascular exercises of low intensity, which provide pain relief through the release of endorphins and the facilitation of fluid and nutrient exchange. Examples of these are swimming and brisk walking.
