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.

Hot and Cold therapy is one of the most popular home remedies for any kind of joint pain or muscle sprain. In some cases applying heat therapy and cold therapy alternatively, can help relieve the pain while for others only one form of therapy is necessary. To understand what to use when, one should first understand the effect of heat and cooling on the body.

Applying a heat pack or immersing the affected limb in hot water improves blood circulation and makes the muscles more flexible. Thus, it can help relax a muscle and fasten the healing of damaged tissues. On the other hand, cold therapy or cryotherapy reduces blood flow to the affected site. This helps relieve inflammation and pain caused by it. It can also make the area feel numb by reducing nerve activity temporarily.

Types of Heat Therapy
Heat therapy can be categorized as dry heat and moist heat. Dry heat involves using saunas or dry heating packs to relieve pain. This is also known as conducted heat therapy. As the name suggests, moist heat involves the use of steamed towels, hot baths and moist heating packs. This is also known as convection heat therapy. Moist heat is usually considered more effective than dry heat.

Types of Cold Therapy
Cold therapy may be applied to a part of the body or to the entire body. This includes ice packs, coolant sprays, ice baths, ice massages and whole body, cold therapy chambers.

How to use heat and cold therapy?
The sooner heat and cold therapy is given to a person, the faster they will recover from their pains. Heat therapy can be given to a person for extended periods of time but when giving cold therapy, a person should not be exposed to a cold pack or ice bath for more than 10-15 minutes. Care should also be taken no to apply ice or a frozen pack directly on the skin as it can damage the skin and nerves.

When not to use Heat Therapy?
If the injury site is swollen or bruised, cold therapy is better than heat therapy. Heat therapy should also not be applied to an open wound. People suffering from conditions such as diabetes, dermatitis, deep vein thrombosis, vascular diseases and multiple sclerosis should also avoid heat therapy as these conditions can increase the risk of burns and other such complications. Pregnant women should also consult a doctor before using a hot tub or sauna.

When not to use Cold Therapy?
Cold therapy is avoidable for treating stiff joints and muscles. People suffering from poor circulation and sensory disorders should also avoid using cold therapy without a doctor s supervision.

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.

Once feared to be highly contagious and fatal, leprosy is today a disease that can be treated and even cured. Leprosy or Hansen s disease is a bacterial infection caused by the bacterium Mycobacterium leprae and affects the peripheral nervous system and skin. Leprosy has been categorized into two types   tuberculoid and lepromatous   with the latter being more severe. Both these categories have been further subdivided into more categories. Skin lesions are the most prominent symptom of leprosy. If left untreated, leprosy can cause permanent damage to the skin, nervous system, limbs and eyes.

An early diagnosis of this disease makes treatment easier. Apart from antibiotics, homeopathic medicines are also effective when it comes to treating leprosy. Homeopathy is a holistic form of treatment that addresses not only the symptoms of the disease, but also the root cause of the infection. One of the biggest advantages of homeopathy is that it has negligible side effects. When it comes to leprosy, homeopathy can be used to reduce inflammation and pain, drain sores and promote suppuration. It can also strengthen the immune system to prevent recurrent sores and boils. Some of the homeopathic remedies that may be helpful are:

Sulphur: If the patient has a tendency to suffer from eruptions, curvature of the spine, wrinkled and flabby skin and has a voracious appetite triggered by diseased glands, sulphur is effective. The symptoms may also be aggravated by washing and the affected area may itch more on scratching. There is a tendency for the folds of the skin to be sore.

Graphites: If the patient has swollen lymph glands, mesenteric glands and prominent skin sores, this medicine is useful. It also treats moist eruptions that bleed or ooze tenacious discharge before turning into scabs on the scalp, face, joints and in the folds of the skin. The patient may experience an absence of sweat and hair fall.

Calcarea Carbonica and Silicea: The combination of these two medicines help in treating a patient who suffers from a swollen abdomen and has open fontanelles. Excessive sweating is another symptom treated by Calcarea carbonica and Silicea.

Rhus Toxicodendron: This is prescribed in cases where the patient has reddish skin that is covered with vesicles and suffers from intense itchiness.

Cantharis: It is used when the patient has large blisters on the skin accompanied by intense burning. The blisters may look like typical burn blisters.

Croton Tiglium: It is used to treat small blisters that itch terribly and form pustules that dry into yellowish scabs.

Although homeopathy is considered safe and free from side effects, it should not be used to self-medicate.

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

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.
