Why does PAIN occur? Understand the Mechanism of Pain

Pain is an unpleasant and distressing physical sensation caused by disease or injury, which induces hurt and anxiety in those suffering from it.
There are many different manifestations of pain, ranging from short term (acute pain) to long term (chronic pain). Other classifications include pain in the internal organs (visceral pain), injured tissue (inflammatory pain), nerves (neuropathic pain), etc.

The reason for the occurrence of pain depends on the cause and kind of pain being experienced. In most cases, pain acts as a warning sign that the body has been afflicted by a disorder of some sort, which may have arisen due to internal sickness or external wounding. Acute pains are generally cured on their own through rest or simple medication. Chronic pains, on the other hand, are more complicated in nature and the treatment requires more elaborate diagnosis.

The mechanism of pain

Pain is an extremely personal and subjective experience and affects each individual to varying degrees. The pain signals, which can arise in any part of the body, travel through the spinal cord to the brain along thousands of specialized nerves and nerve fibres. In the brain, it is processed in the centres associated with anxiety, emotions, memory, appetite, etc. Signals and pain inputs are then returned from the brain to the spinal cord, which may heighten or diminish pain.

In some cases, pain may also be induced by damage to the brain and spinal cord, which happens after a stroke.
A constant barrage of pain signals may cause the cells at the end of nerve fibres to become over-sensitized. This is known as 'wind-up' and is one of the most common causes of chronic pain that occurs even though the root of the problem has been identified and treated.

The causes and effects of pain differ from case to case depending on the signals received by the brain and its interpretation. It affects the individual's day to day activities and if persistent, can also have a harmful impact on mental health and psychosis. Pain is always handled, diagnosed and treated differently in all patients by drawing out the best possible solution to the problem.

Shoulder pain can be a persistent dull and nagging sensation in the upper arm or shoulder area. It can be easily differentiated from neck pain as it is related to the movement of shoulders i.e. it will increase and decrease with shoulder movements, especially overhead activities. The other signs to identify shoulder pain is if your shoulder movements are reduced.

If you find it difficult to scratch / wash your back, comb your hair or reach your back pocket, it clearly shows you are suffering from shoulder pain. Shoulder pain can happen due to various reasons, it varies from person to person depending on the activities he/she is involved in, for e.g. sports, manual job etc. It can be a single major injury or multiple small injuries due to repetitive usage patterns. Also, degenerative changes in various parts of the shoulder can lead to shoulder pain.

In case of middle to old age, injuries that can cause shoulder pain are:

    Biceps Tendonitis
    Acromio-clavicular Joint arthritis
    Scapular Dyskinesia
    Trapezitis
    Suprascapular nerve entrapment In young age, injury due to sports or gym activity can cause shoulder pain
    Superior labral anterior/posterior (SLAP tear)lesion

Also, traumatic or repeated dislocations of shoulder can cause shoulder pain due to:

    Bankart lesion

Diagnose Shoulder Pain

Shoulder pain can be diagnosed only after thorough history taking and clinical examination. However, some imaging studies can be very helpful like:

    X-rays: Through an x-ray one can view the shoulder in many different views.
    Ultrasound: With an ultrasound, you can also check the damaged caused to the tendons and muscles of the shoulder but the quality of reporting depends upon the expertise of the doctor.
    MRI: MRI gives a clear picture of the shoulder as it shows everything related to a shoulder joint that is joints, vessels, tendons and muscles that too from different angles.
    Diagnostic Arthroscopy: A surgical procedure often used by orthopaedic surgeons to diagnose and treat issues inside a joint. Arthroscopy has the big advantage that one can use it to diagnose as well as treat at the same time.

Treatment for Various Types of Shoulder Pain

    For Shoulder Impingement or Rotator Cuff tear: Give rest to the shoulder for a few days only Dedicated Physiotherapy Protocol Bursal injections If these fail then, (Surgery)Arthroscopic sub-acromial decompression If Cuff tear is found, then one can go for Arthroscopic/Mini-open repair
    Labral Lesions: For anterior Labral lesions (Bankart's) following anterior shoulder dislocation then surgery in the form of Arthroscopic Bankart's repair is the only option to reduce risk of recurrence and degeneration.

SLAP Lesions

    Pain relief and physiotherapy as first step If this fails then following surgical options are available
    Arthroscopic debridement or repair of labrum
    Biceps tenotomy or tenodesis

Arthritis

In this case, the joint is already destroyed and has to be resurfaced for pain relief and to maintain ROM. If Rotator cuff muscles are working, then Shoulder resurfacing hemiarthroplasty (preferred in young people), that has a life of 10 to 15 years, Total shoulder replacement (preferred in middle aged to old people) has a life of 10 to 15 years. But, if rotator cuff muscle are not working then Reverse Geometry Shoulder replacement is recommended, that has a life of 10 years.

It is always advisable to get yourself diagnosed properly in case of shoulder pain as management changes depending on clinical situations. Neglecting shoulder conditions can lead to bigger problems later on.

Always remember 'a stitch in time saves nine'

Shoulder Pain: Causes, Diagnoses & Treatment

Vertebroplasty means shaping the backbone i.e. vertebra for backbone and plasty is related to shape. This is an outpatient procedure done to treat compression fractures of the spinal cord. The backbone is made up of multiple small bones which are stacked one on top of the other with a filling material in between that is known as vertebrae. The stack of bones are held in place by the soft, elastic vertebral material. 

Vertebroplasty & similar procedure called kyphoplasty is a non-surgical procedure where collapsed vertebrae is brought back to shape by injecting medical bone cement under fluroscopy / image intensifier in OT, thereby relieving pressure on the spinal cord or spinal nerves with special canula directed to the core of vertebral body. Indicated in osteoporotic vertebrae, spinal fracture, metastatic tumour or primary tumour of spine. This technique has replaced major surgery done earlier to reshape & fix vertabrae.

Technique: Bone cement, in a semisolid state, is injected into the weakened or fractured bone space. Once this solidifies, it provides additional support to the spine, enabling normal movement. It also helps in reducing the pain significantly and improves the overall mobility.

Procedure:

In what takes about an hour, the following steps are done. Earlier, a few decades ago, this would be an open surgical procedure. However, with advance technology, now it is done using a small incision

Local anesthesia is given in the area that needs to be operated
A biopsy needle is inserted into the fractured space with the help of an X-ray
The acrylic bone cement is injected into the bone space with a needle to fill up the space, once it solidifies, it stabilizes the vertebral space
The needle is removed and the incision is covered with a bandage
Usually the patient is sent home in an hour s time unless the overall condition is really bad
There could be some soreness at the site where injection is given, but one can notice a significant reduction in pain from the day of the procedure
There is also improvement in mobility while doing daily chores
The pain relief can last up to 3 years after the procedure
Returning back to normal activities takes about 3 to 4 days after the procedure
When to use this procedure?

Vertebroplasty is usually done in case of non-radicular pain that is intractable. In most cases, they do not respond to traditional therapies including physiotherapy, pain medications and even surgery. The pain could be due to:

Osteoporosis
Cancer metastasis
Myeloma
Spinal hemangiomas
Traumatic fractures
Benefits of using vertebroplasty for managing pain 

Minimally invasive
Effective way to get relief
Improves mobility
Cost-effective
Reduces need for long-term use of painkillers
Stabilizes the spine and prevents further collapse

Vertebroplasty - How It Can Help Manage Pain?

Dysmenorrhea is a condition marked by severe menstrual cramps. This is caused due to contractions in the pelvic area during the menstrual cycle. While most women go through some degree of cramping, when the cramps become too serious and severe, it should be reported to a doctor to find out if there are any other related problems like Endometriosis, Fibroids, Adenomyosis or some infections.

Here are the ways in which this condition may be treated effectively:

Medication: One of the main ways of dealing with this condition includes taking pain relievers that must be prescribed by your doctor. Also, one can take over the counter drugs to relieve the pain. These include ibuprofen as well as aspirin and non-steroidal anti-inflammatory drugs. Acetaminophen can also help in most cases. Some women may need antibiotics to take care of pelvic infections that cause pain in the pelvic region.

Hormonal Birth Control: if your symptoms are too severe and debilitating, then the doctor can also put you on hormonal birth control treatment to bring down the pain and severity of the cramps. These are usually prescribed in the form of oral tablets which need to be consumed daily as advised by the Gynaecologist . Sometimes, some women may be unsuitable / unwilling for oral medications and in such cases, other routes for hormonal administration may be followed. This can be administered in the form of an injection. Also, you may wear the dose as a patch on the skin. A surgical procedure can also implant the same under your skin. This also comes as a flexible ring that the doctor can insert into your vagina with the help of an intrauterine device (IUD).

Surgery: In very extreme cases, the doctor may recommend surgery. This is usually conducted in case there is an underlying condition like endometriosis or fibroids, which can create severe complications for the patient as well. The doctor may also carry out surgical removal of the patient's uterus in case there are many complications.

Home remedies: One can exercise on a regular basis in a moderate manner so as to ensure that the cramps are not too severe. Also, you can use heat therapy in order to bring down the pain. This can be done by taking a hot bath and soaking in a tub of hot water. Also, you can use a heat compress so as to relieve the pain. Other dietary supplements can also be taken in order to reduce the cramps. For this purpose, one should regularly indulge in fish and flax seeds as well as other ingredients that are rich in omega three fatty acids. Also, vitamin B1 is an important ingredient that can be found in leafy green vegetables. Magnesium supplements can also be taken by the patient for such cramps.

Stress: one will need to take care of the stress levels by staying away from stressful situations and also cutting back on the consumption of alcohol. One should also avoid smoking completely. Meditation & Yoga have been known to help in relieving stress and you can practise a little bit of these on a daily basis. Also, devoting time to your hobbies and listening to good music can be a stress-buster when incorporated in your daily routine.

So eat right, exercise right, think right and have a positive attitude- That helps take care of most non-pathological cases of dysmenorrhoea.

Ways to Treat Dysmenorrhea Effectively

Problems with the arteries and veins present in the hands or legs can lead to vascular disorders. The arteries carry blood from the heart to other parts of the body in order to deliver nutrients and oxygen. The veins carry the blood back to the heart, after the nutrients have been used up. If these blood vessels of the arteries or veins become blocked or narrowed, it can lead to a vascular blockage.

A vascular blockage that occurs in the hands or legs comes under the category of Peripheral Artery Disease or PAD. These type of disorders are less common in the upper extremities of the arms or hands than in the lower extremities of legs. Few of the signs for the same are:

Pain and difficulty in movement due to decreased blood flow
Numbness or weakness of leg or fingertips
Sores on the toes or feet
If the blockage is deep, symptoms of redness, swelling, extreme pain or cramping can be experienced
Abnormal color changes in the fingertips
Ulcers or wounds that don t heal
Skin sensitivity problems when in cold temperatures
How can it be diagnosed?
The blockage can be detected by various methods namely-

Physical Examination   Your doctor may find decreased pulse at armpit, wrist or fingers, full veins, masses, wounds or gangrene.
Doppler or Ultrasound examination to determine the blood flow in the arteries and veins
MRI Scan of the affected area to pay special attention to the blood vessels
Cold Stress Test
Arteriography to show clear blood vessel details
Angiography to map blockages and narrowing of the arteries
What are the Risk Factors for Peripheral Artery Disease?
An individual is at risk for developing vascular blockages in the hands or legs if one or more of the following factors are present:

Smoking
Diabetes
Heredity Factors   A personal or family history of blood vessel disease
High blood pressure
High cholesterol
Aging   People aged above 50 years and older are more prone to vascular blockage
Can it be treated?
Treatments for vascular blockage can vary depending on the age, cause of the blockage, intensity and overall well-being.

Treatments can include:

Self-care   Reducing risk factors and making lifestyle changes to quit smoking, sedentary life or diabetes, blood pressure and cholesterol management can reverse symptoms of vascular disease.
Medications   A variety of drugs can be prescribed to lower the risk and progression of narrowing blood vessels or prevent blood clotting.
Interventional Procedures   Minimally invasive surgery like saloon angioplasty, stenting or removal of artery plaque build-up.
Surgery   If the blockage is severe, surgery may be performed to lessen the vessel narrowing, reconstruct the artery or tie it off, depending on the circumstances.

Pain in the Hands or Legs!

The toes and heels are the most load bearing components within your feet which take most of the weight when walking, running, exercising or even standing up. The heels are an especially vulnerable part of the body which can become painful either due to injuries or excessive stress put on it. Pain in your heels can also be a sign of other problems in your body.

Causes for heel pain:

1. Sprains or straining the leg: Exercising is one of the most common culprits behind heel damage. Wearing the wrong shoes over prolonged periods, which can cause your balance to be shifted and will lead you to put strain on your heels and cause pain. Falling or spraining during exercising or training can also cause heel pain.

2. Fractures: Stress or hairline fractures can occur even without impacts or trauma and also cause pain. It will slowly build up over time. In such cases, you should immediately consult a doctor and take remedial action.

3. Achilles tendon: A common cause for heel pain, the Achilles tendon connects the calf muscle to the heel. If this is torn or damaged, it can cause pain in your heel.

4. Arthritis: The deposition of uric acid crystals in parts of your body may result in arthritis; this is a fairly common cause for heel pain as well.

Treatments available

1. Change in shoes: Shoes play a major role in the development of heel pain. You will either need to change the shoes or adjust the heels to ensure that they are at an equal and comfortable height and keep your posture natural and balanced.

2. Foot supports: There are specialized heel supports and wedges, which you can wear with the footwear. These supports help redistribute weight from the problem areas and uniformly distribute it among the other parts of the foot. Heel cups are also another form of supports you could try.

3. Pain relief medications: Sometimes aspirin or ibuprofen may be required to numb and dull the pain, if getting through the day becomes difficult or you are in the middle of work.

4. Resting: Sometimes resting is the only medication you can take to relieve the pain as it can only subside once the underlying conditions are corrected.

5. Ice packs: Cold compress and cold therapy would definitely help in numbing the area and providing temporary pain relief.

It is however, advisable to visit the doctor if the pain persists and take specialized medical care in more complicated cases wherein the pain is prolonged.
