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 something that affects many people all over the world. Persistent and chronic pain seems to be one of the most common complaints. Middle back pain is back pain that is felt in the thoracic vertebrae region, which is located between the base of the neck and top of the lumbar spine. The ribs attach to a long, flat bone in the middle of the chest called the sternum and wrap around the back. In case, there is a nerve around there is squeezed, disturbed, or injured, you are likely to feel pain in different spots where the nerve goes through, for example, your arms, legs, chest and the stomach.

Some of the most common causes of middle back pain are as follows:

Middle back pain can happen as a consequence of injury or sudden damage or it can happen through strain or poor stance after some time.
The most widely recognized reason for middle back pain seems to begin from soft tissue problems or muscular irritation. These can emerge from poor stance, lack of strength, prolonged sitting in front of a computer, utilizing a heavy backpack, overuse injuries, (for example, repetitive movement), or injury, (like a whiplash damage brought about by an auto crash or as a consequence of a sports injuries).
The middle back is a moderately normal site for inflammatory, degenerative, metabolic, infective and neoplastic conditions.
Middle back pain and its dysfunctions are connected with various conditions, for example, essential and optional osteoporosis (particularly vertebral cracks and hyperkyphosis emerging from vertebral bone loss), ankylosing spondylitis, osteoarthritis and Scheuermann's infection.
Muscle strain, overuse or damage to the muscles, tendons, and discs that are backing your spine can also cause middle back pain.
Weight on the spinal nerves from specific issues, for example, a herniated disc.
A fracture in one of the vertebrae can also cause pain in this region.
Osteoarthritis created by the breakdown of ligament or cartilage that cushions the little joints in the spine.
Myofascial pain that influences the connective tissue of a muscle or gathering of muscles.
In uncommon cases, pain might be brought about by different issues, for example, gall bladder disease, cancer or an infection.
Getting hit hard in the back can also cause chronic pain.
Lift something too heavy may cause pain and a sudden pressure in this area.
A compression fracture of the vertebra can also bring about intense or chronic pain in the middle back. The injury may bring about a fracture, however in ladies over age 50 without critical injury or somebody known to have osteoporosis, an unconstrained vertebral fracture is possible.
Other contributing factors to injury include lack of strength which can be treated by a Pain Management Specialist using non-surgical methods.

Common Treatment Options For Back Pain

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.
