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.

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.

Nerve Pain - 7 Ways You Can Control it 

Body pain and Physiotherapy

Physiotherapy is an effective way to reduce various kinds of body pains. Physiotherapy includes massages, exercises, and heat treatments to relieve pain. This treatment is often recommended as the first option to treat back and neck pain. Physiotherapy is also used to rehabilitate patients after surgery. Different kinds of exercises included in this treatment are also useful to treat sports injuries.  Here are some steps that you can take to relieve your body pain incorporating physiotherapy.

Get appropriate help

It is important to properly diagnose your condition before going for physical therapy. Seek help from a professional and if he/she recommends physiotherapy then only opt for the treatment.

Reduce your severe pain before exercising

If you are in immense pain, work to alleviate the pain before engaging in exercises. Cold/ hot therapy, massage, manual manipulation are some of the methods that can slowly reduce the pain. These are all part of physical therapy.

Exercise

Exercising has numerous health benefits including relieving back pain. As you age, your back tends to get weaker; it is important to workout to prevent future backaches. Stretching, strengthening and low- impact aerobics are ideal for this issue.

You can also try water therapy as water has a therapeutic effect on pain and makes your movements much easier than on land.

Observe your body's reaction to physical therapy

When you have just had a back or neck pain episode and try physical therapy you will feel some initial discomfort, it is expected. After you acclimatize yourself with the routine all kinds of pain will gradually diminish. The initial pain due to physiotherapy is caused because your muscles are stiff and they are being stretched the way they are not used to. However if the pain gradually increases you are probably not right for that particular kind of physical therapy.



Body pain and Physiotherapy

Pain management is an issue that stares back at mankind, irrespective of the underlying health condition. Whether it is a headache or a back pain, burn or fracture, heart attack or cancer, pain is always a symptom. In some cases like migraines, cancer, etc., the pain is chronic and the patient needs to be constantly on the vigil to know when an attack will ensue. This has also put high pressure on the medical fraternity to identify ways that can provide relief to these people. Various methods have been identified, and one of them is the electrotherapy.

What is done?
A few electrical impulses are directed at the area of the pain using a hand-held device. This is similar to providing electric shocks of mild intensity to the affected area (forehead, low back, neck, etc.). What this does is stimulate the nerve endings, improves circulation and muscle strength and promotes bone growth and tissue repair. The end result of all this is overall improved functioning and pain relief. Depending on the actual condition, the sessions will have to be repeated. In some patients, the electrotherapy is used in conjunction with other therapy so that they can go about their routine exercise and pain relief.
The sessions may also have to be repeated as most often these are used in individuals with chronic pain. They are also helpful in providing relief during the acute attacks.

How does it work?
The most common form of electrotherapy is known as TENS, which stands for transcutaneous electrical nerve stimulation. The area to be treated is cleansed with spirit and then small sticky pads are applied through which the electricity is passed. A hand-held device is used, through which electrical impulses are passed to the skin, which stimulates the nerve cells to provide relief from pain. It causes a vibrating and tingling sensation in the treated area. It is believed that it blocks the nerve impulses and therefore provides pain relief. Another theory states that they promote the release of endorphins which are natural painkillers; it is also very effective in case of migraine and sciatica and neck pain where the chronic pain is coupled with acute spurts.

With narcotic painkillers having various side effects, techniques like electrotherapy are gaining popularity. A small catch also is that it does not work for everybody and in most people with back pain, fibromyalgia, and migraines, requires repeat sessions for relief. The cost of each session also needs to be considered against the extent of relief achieved. However, for those whom it works, it is a very good technique for chronic pain control.

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

Prevention of leprosy: Leprosy is caused by the bacterial infection of Mycobacterium leprae and it is classified into multiple types. Leprosy is communicable through contact with common objects or a person by infected droplets within their nose. It primarily affects mucous membranes and the skin and the nerves on the hands, feet, and in extreme cases may cause disfigurement as well. There are no specific ways to prevent leprosy as no specific correlation between transmission and development has been found so far. Leprosy can happen through one time contact or through contact over extended period of time within the same household. Thus preventive measures will primarily include the following:

Regular checkups by going to the doctor
Ensuring that surfaces are kept clean if you share a household with a leprosy patient
Skin biopsies at regular intervals just to check if you may have contracted the bacteria
If a rash has developed, then it is urgent that you visit the doctor. Earlier the leprosy is detected, quickly it can treated and resolved
Incidences of leprosy have reduced over the last few decades due to improvements in medicine and early detection. This has allowed people to nip the problem in the bud and does not allow it to spread within their bodies or to other people.

Treatment of leprosy: The primary weapon that modern medicine has against leprosy is known as MDT or multidrug therapy. Multidrug therapy is the combination of multiple drugs, which attack the various aspects of leprosy, such as skin problems, nerve damage, loss of sensation, deterioration of skin conditions etc. This is the proven way to not only reduce symptoms, but also cure the problems in the long run.

Some of the drugs in the MDT used are as follows:

Rifampicin and dapsone
Rifampicin and clofazimine and dapsone
Rifampicin, minocycline and ofloxacin
However, the combination will depend on the type of leprosy the person is affected with, such as paucibacillary leprosy or multibacillary leprosy and thus can only be prescribed by the doctor after the thorough and detailed examination.
