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.





Why does PAIN occur? Understand the Mechanism of Pain

In recent times, there has been an upsurge in the instances of leg pain. People from all age groups, irrespective of their gender, are being affected. Needless to say, this painful and uncomfortable condition throws life in jeopardy and adversely affects and interfers with a person's daily activities. While the pain can be in both the legs, many people also suffer from severe radiating pain in one leg.

What causes radiating pain in one leg?
More than often, this kind of pain is triggered by nerve problem or disorder. If you experience a shooting pain that originates in the lower back and gradually radiates down to one of the legs (from the buttocks to the back of the leg), chances are you are experiencing sciatica.

In sciatica, the nerve affected is the sciatic nerve. The sciatic nerves originate from the spinal nerves L4 to S3. From the lower back, the nerves (two sciatic nerves) extend downwards to the back of each leg. The sciatic nerves further divide into a tibial and peroneal nerve. These nerves are mostly responsible for the sensation and motor functions of the legs and the feet.

Sciatica can be an outcome of
The discs present between the vertebrae provides them with a much-needed cushion, preventing injury or damage. In case, of a degenerative disorder of the disc, the protective cushion gets affected resulting in the pain and associated symptoms.

Lumbar spinal stenosis: A medical condition where the spinal canal in the lumbar area narrows down, exerting pressure on the sciatic nerve.
Spondylolisthesis or a slip disc: The condition mostly affects the lumbar area (base of the spine) whereby there is slippage of one of the bones over the adjacent bone (the bone located just below it).
A muscle pull in the buttocks can also trigger sciatica and many times, a pregnant woman may also experience sciatica. The sciatic pain can be:

Chronic sciatic pain: As the name suggests, chronic sciatic pain is intense and more severe, with the symptoms persisting for a longer time (more than three months). Arthritis, severe nerve damage or scarring (tissues) are often responsible for chronic sciatic pain.
Acute sciatic pain: An injury to the nerves, muscles, spinal joints or discs can cause the pain. However, as instantly as the pain starts, the condition improves within days (at times weeks).
In addition to the radiating pain, there may be other symptoms associated with sciatica such as

Difficulting in leg or foot movement.
Weakness
Sciatica can also trigger a pain in the back of the leg which aggravates when a person is in a sitting position
Hip pain
Numbness, and often a tingling or burning sensation radiating down the leg
In some people, sciatica can cause a shooting pain (which worsens when a person tries to stand up)
The pain (in some cases) can extend to the foot and toes
There can be many underlying factors responsible for the pain radiating to one leg. Neglecting the condition will only worsen the situation further.

Stitches or sutures act as a closure for either surface wounds or deep wounds. Procedure to close a deep wound comprises of sewing the two edges and applying stitches under the skin surface.

Catagories of sutures

    Non-absorbable stitches: Such stitches are applied in case of skin wounds or internal wounds. Such stitches get healed quickly and are easy to remove. Non-absorbable stitches are made of natural fibers or synthetic threads like nylon polypropylene. As the name suggests, these stitches are either permanent or persist for a long time.
    Absorbable stitches: Such stitches are applied on layers, which have the property of healing quickly. They are very firm during the initial days. Then they start getting dissolved in the body.

Precautions taken by medical team before applying stitches to prevent infection

    Careful checking of nose for occurrence of germs before the start of operation.
    Skin must be cleansed prior to surgery.

Pain in Stiches - When You Should See Your Doctor?

Restless leg syndrome is a condition where the nervous supply to the lower legs (and sometimes hands) is affected. The person has a constant urge to move the legs due to the tingly sensation or the pins and needles sensation and so this condition is called as restless legs syndrome (RLS). It is almost never a standalone condition and is often associated with other nervous system conditions.
It is a progressive condition and aggravates with time. The patient may experience episodes of this disease. Most people might experience this problem at night due to which a lot of patients complain of disturbed sleep and restlessness while sleeping.

While there is no permanent solution to this condition, there are various home remedies and techniques which can help control the condition. Read on to know more.

Trigger agents: Some people are able to identify triggers like caffeine or chocolate which induce the condition. The first step would then be to avoid using these, especially before sleeping.
Exercise: Any form of exercise, which gives a good workout for the leg muscles is recommended. This could range from a 30-minute brisk walk to stretches depending on the person s overall health status. This is known to induce a good sleep, reduce muscle tension and relax the mood. Choose yoga, gym, cycling, or any form which suits your overall health and schedule.
Massages:Hot or cold massages, often used alternately, can help in relaxing the muscles. This also helps in reducing tension and improving overall sleep. The ideal time for the massage is the evening so that RLS does not affect during nighttime.
Diet: A diet rich in vitamins and minerals can prove to be helpful. This is because proper muscle and nerve function requires various minerals like zinc, potassium, calcium, sodium, etc. Diet rich in these helps in improving muscle and nerve function and thereby control RLS.
Sleep pattern: Sound sleep practices like having an early dinner, a quiet room free of digital media, optimal temperature, and relaxing ambience helps in a better sleep. This has shown to reduce the incidence of RLS and evidence of sound sleep.
Medications: RLS can also cause mild to moderate pain in the affected legs, and so pain killers can be used once in a while if the pain is not bearable. These should be used only rarely and continued use can lead to stomach ulcers and bleeding. The above mentioned nonmedical methods should be tried before trying medications. Anticonvulsants have been used to control RLS if pain killers alone are not adequate. In more severe cases, antiparkinson drugs are used with great success.

Restless Leg Syndrome - How It Can Be Controlled?

How To Control Nerve Pain?
Nerve pain or peripheral neuropathy, as it is medically known, is characterized by pain, numbness and weakness that arise out of nerve damage. This pain is usually restricted to the feet and the hands.
What are the common causes?
Diabetes is the most common cause for this condition. However, other causes, such as injuries, infections and prolonged exposure to certain toxins can also trigger nerve pain.
How can you control nerve pain?
Nerve pain can be managed and taken care of at home taking into consideration the points that have been mentioned below:
Topical Painkillers: Certain over the counter ointments and creams can help relieve nerve pain. These medications act as local anesthetics; that is they numb the area of the pain. Capsaicin, a derivative of chili peppers, is one of the major ingredients used in these medicines. Others use botanical oils as the major ingredients.
Painkillers: There are painkillers available OTC which can curb nerve pain. However, painkillers such as ibuprofen, aspirin and acetaminophen do not really work well for severe pain of the nerves.
Supplements: The lack of Vitamin B12 is considered to be a very important cause, and at times, a catalyst for nerve pain. In a case such as this, Vitamin B12 supplements or injections might be administered. Although more research needs to go into this, but certain supplements, especially gamma-linolenic and alpha-lipoic acid can help soothe nerve pain caused by diabetes.
Acupuncture: This time honored Chinese approach is a proven alleviator of nerve pain. Acupuncture releases chemicals which numb the pain, or prevent the pain signals from travelling to the brain.
Physical Therapy and Massages: Physical Therapy can especially heal and strengthen weak muscles that can stem from acute nerve damage and pain. Though more evidence is needed, according to a few sufferers of this condition, massages can be helpful with the tremendously painful muscle spasms that can so often result from nerve pain.
Relaxation Techniques: In combination with the above mentioned approaches, relaxation techniques can go a long way in relieving debilitating neural pain. Besides being helpful with dealing and reducing a few stress phases of life which can cause nerve pain, these techniques might actually root out the actual pain itself.
Lifestyle Modifications: This one s always a winner! Eating a well-balanced diet that guarantees all nutrients in uniform amounts can never go wrong. Regular exercises for about 30-45 minutes can remedy different types of pain; nerve pain being one of them. Try and limit alcohol intake (a peg once a week won t harm one, but binge drinking can play the ultimate spoilsport and make all health plans go topsy-turvy!). Abstain from smoking or chewing tobacco as this is usually the primary contributor towards any medical condition or disorder.
