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

Today  working  usually implies sitting at a desk from morning to evening. While this may seem more comfortable than working in the fields, sitting at a desk can trigger a host of back problems. This is because sitting in the same position all day makes the spine bend forward and lowers the efficiency of the back muscles. Working at a desk not only strains your back, but also restricts your movements to typing on a keyboard and moving a mouse. 

Once a back problem begins, it usually lasts a lifetime hence; here are a few tips to save your back.

Get yourself a good chair: Your chair is crucial to your back s health. Avoid the hard backed plastic chairs and pick a more flexible mesh backed office chair if you sit at the table for a long span of time. Ergonomic chairs may seem expensive, but are worth the expense in the long run.
Stretch your muscles: Sitting in the same position all day, puts the muscles under stress and with time can constrict the muscles. Make it appoint to stand up every 30 minutes and stretch your back and sides. Also try rotating your hips and shoulders form time to time.
Take a break: No matter how much work you have in front of you, take a break at the end of each hour. Taking even 2 minutes off out of 60 every hour can have a huge impact on your health. If you still feel guilty skip using the phone to connect with your colleague and walk over to their desks instead.
Get a pedometer: Keeping a pedometer will help you track the number of steps taken in a day. Ideally, a person should take 10,000 steps a day to stay healthy. If you sit at a desk for majority of the day, take every opportunity you can to up the count on your pedometer. Go for a walk around your office after lunch or park your car a little way off from the office to create opportunities to walk.
Take the stairs: As far as possible avoid escalators and elevators. Instead climb stairs for a quick workout. If your office is on the 20th floor, walking up may not be feasible, but you could get off the elevator on the 18th floor and walk up the remaining two floors.
Eat healthy: Lastly, pay attention to what you eat. Avoid eating at the office canteen or picking up a bite at the coffee shop and carry lunch from home. This ensures that you eat a balanced meal.

Long Hours Of Sitting? Try This Permanent Relief From 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.

3 Essential Tips to Prevent Back Pain

Pain is unpleasant suffering caused by injury or illness. Back pain may be sudden/constant, dull, severe or not responding to short rest and medication. Constant pain in back in any region of spine for more than few days to weeks needs intervention.

Pain which is intense especially at night requires urgent visit to a specialist.

Sudden onset of pain in back with or without injury needs urgent attention.

Back pain with difficulty in walking, pain while getting up from position of comfort, pain during change of posture or pain after prolonged sitting (for work) can lead to serious permanent damage, if left untreated.

Pain which travels to one or both legs may be due to pressure on the nerve/s and if left untreated for long can lead to permanent weakness or damage.

Pain associated with numbness, tingling or weakness in legs, especially below the knees, commonly called Sciatica, needs to be investigated. Various spinal ailments can lead to weakness in one or two limbs or all four limbs. There may be associated or isolated numbness (loss of sensation to touch, pain or temperature) without back pain.

Numbness, tingling or weakness may be the only symptoms without any complaint or without history of back pain.

Problems related to bladder control which may be difficulty to control, hesitancy in passing or dribbling of urine. There may be associated constipation. Loss of bowel/bladder control is caused by pressure on spinal cord &/or nerves which may be due to injury, infection, disc prolapse or tumor.

Sudden swelling and redness in back usually happens after an injury or accident but sometimes are signs of underlying severe illness.

Loss of normal shape/curvatures of spine can present with or without pain. It can lead to forward, sideways or rarely backward bending.

Unintentional weight loss, loss of appetite, evening rise of fever or disturbed sleep with associated back pain/weakness/numbness needs visit to a specialist.
