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

Back pain is a common source of pain and can be acute, sub-acute or chronic in nature. Back pain is classified along the segments of the spine and can be divided into neck pain, middle back pain, lower back pain and coccydynia or tail bone pain. Back pain can be quite troublesome as it disables a person to move about freely due to constant ache.

Here are some procedures for the treatment of back pain.

    Give your back some rest: Most people who get back pain become obsessed with it and end up getting MRI scans and x-rays done. Some even take injections and other such measures without recognizing the intensity of the pain. It is advised not to rush into the matter immediately and the simplest way to cure the pain is by resting. 90% of pains in the back resolve by themselves in 6 weeks and so you must give your back a break instead of taking medical actions and let time do the healing.
    Pills: While you let time treat your back pain, sometimes the pain increases and gives you a bad time. In this case, you can take anti-inflammatory medicinal pills such as ibuprofen or naproxen. These pills will help you ease the pain. However, using such pills for a continued period of time causes side effects such as gastrointestinal disorders. Hence, you should not take them for more than ten days at a stretch.
    Hot and cold compress: Apply a bag of frozen peas or an ice pack to the affected area for 48 hours after the pain appears. Every session should be about 20 minutes, and you should take more than two sessions each day. After two days, repeat the same procedure using a heat pad instead of ice. The cooling procedure shuts down your blood capillaries and reduces the flow of blood to that area. The swelling is eased as a result. The heating, on the other hand, loosens tight muscles and increases the blood circulation, providing extra oxygen.
    Change your mattress: People who sleep on firm mattresses and cushions on their beds are at a higher risk of having a back pain. According to studies, it has been observed that people sleeping on medium-firm mattresses have healthier backs. In case your mattress in sagging or is over 8 years old, you should replace it.
    Acupuncture: When your back pain is very severe, you can resort to acupuncture, which provides efficient pain relief. The procedure changes the way your nerves react and reduces inflammation.

Back pain arises from various reasons and should always be taken care of. Unattended back pain worsens and makes the affected person suffer.

Suffering From Lower Back Pain - 5 Ways You Can Treat it

Back pain is one of the most common debilitating disorder in the world today. The pain affects 90% of people at some point of their lives. Human back comprises of various structures (see figure) which are nerves, bones, muscles, ligaments, and tendons, any or all of which can be a source of pain. Once back pain occurs, it may become chronic (more than 4 weeks) and you shall need to consult a pain physician for relief and accurate diagnosis.
Since prevention is always better than cure,  you can save yourself from having back pain if you follow these basic tips.
Regular Exercise in Correct Form: Regular exercise is important to maintain proper muscular strength of the back. Human back is supported by several big muscle groups (see figure). They serve two functions - one is to facilitate the posture and movements of the back itself and the other is to help movements of the rest of the body appendages (arms, head, pelvis and legs).The health of these muscle group is important to take stress off the spinal bones and maintain proper function. Most of these muscles are red muscle fibers as they need to maintain their activity for prolonged periods of time. Just to give you an idea - your biceps (arm muscles) have to work only when you bend your arm. But your back muscles have to function all the time - whether you sit, walk, stand or even sleep. But the point is what kind of exercises are good for your back? The best exercises for back include body weight low impact aerobics like brisk walking, swimming, stationary bicycling, extension exercises and yoga. What is important to remember while doing these exercises if that you need to be gentle in your movements and achieve correct "form" - this is possible if you can ask someone (preferably a trainer) to observe and point out whether the back stays straight during the exercise. It has been seen that arching and excessive bending is associated with injury to the back while exercising.
Stay Hydrated and Eat Natural Nutritious diet:The inter vertebral discs contain 70 - 80% water. The muscles and tissues have 60% water content. Therefore, it is important to stay hydrated. In addition, you must eat a nutritious diet consisting of green leafy vegetables, good protein source and just enough carbohydrates. Deficiencies of essential nutrients like Vitamin D can result in diseases like osteoporosis. Another important aspect is to maintain body weight within healthy limits. This is very important as increased belly fat is linked to increased back pain due to mechanical factors.
Lift objects correctly and maintain proper posture:While lifting objects, keep them as close to body as possible. Do not slouch or bend excessively while lifting. Just keep your back straight at all times. You may bend your knees a little if required (see figure). Think before you lift and get help if needed.
While working, you must not sit for more than 45 minutes at a stretch. Walk for two minutes, go to a colleague's desk and say hi or even just drink some water or visit the washroom. Humans evolved as hunter - gatherers and our bodies are more adapted to walking / standing than to sitting for prolonged periods. Those of you who travel more and have to sit for long periods of time also need to follow above tips - avoid prolonged sitting in same posture.While exercising, improper position can do more harm than good. Therefore, proper form and posture is a must.
Bonus tip: Avoid cigarette smoking and those who smoke cigarettes to decrease your chances of having degenerative disc diseases leading to chronic back pain early in life.
Word of caution to prevent permanent damage: In case of back pain, which is not responding to home remedies or over the counter painkillers, please contact a Pain Physician to pinpoint the diagnosis and appropriate management.

In most cases, a little bit of rest does the trick. However, if the lower back pain persists for 3-6 weeks, physiotherapy is recommended.

How does physiotherapy help?

The main purpose behind physiotherapy is reducing lower back pain and increasing muscle and bone function, so that such instances are avoided in the future. Physiotherapy is the first line of defence against lower back pain. More drastic measures such as surgery are undertaken once physiotherapy fails to do is job.

Physiotherapy is often recommended when the back pain is caused due to lifestyle factors, a minor injury like a fall or other moderate factors. For more severe back injuries, doctors recommend surgery straight away when there is no scope of performing physiotherapy.

Low-intensity back pain can be cured using a combination of heat packs, ultrasound wave therapy and Iontophoresis (using a localized current source to introduce medical ionic compounds to the body).
