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.

Pain related sleep disruption has affected a large number of people around the globe. Statistics has it that, in India, about 25% of the population suffers from pain-related sleep deprivation. Studies call it  the vicious cycle of pain and sleep  as pain affects your ability to sleep and lack of sleep makes the pain even worse.

Back pain and arthritis are examples of some common pain-related medical disorders. People with these types of chronic pains have reported persistent sleeplessness or have had immense trouble falling asleep.

The following are the primary sleep disorders associated with chronic pain:

Insomnia: It is a medical condition that is characterized by an inability to fall asleep no matter how physically exhausted you are. Insomnia can be acute (lasting for one night to a week) or chronic (that lasts for more than 3 weeks).
Hypersomnia: It is a condition wherein you tend to sleep excessively; in this condition, you will have trouble being awake throughout the day or can fall asleep at any point of time.
Sleep Apnoea: This is a sleep disorder wherein breathing pauses and resumes repeatedly. Risk factors include obesity, age and gender; it is more commonly observed in men. This condition can be chronic with symptoms such as snoring loudly or feeling very tired even after one has had a night s sleep.
Restless leg syndrome: It is a sleep disorder wherein you continuously move your legs while sleeping. However, this condition can also cause you to move your legs even if you aren t sleeping.
Some of the causes of sleep disorders due to chronic pain are:

Pain
Worry and anxiety
Sweating at night
Depression and other mental disorders
Treatment

A pain and sleep disorder should be simultaneous as both the components of it, pain and sleep, are interrelated. Some of the ways people with chronic pain can still have a good night s sleep are:

Limiting caffeine intake
Abstaining from alcohol and smoking, as these disrupt the sleep cycles, thus aggravating the existing pain.
Practicing meditation and other relaxation techniques
Pain killers or sleeping pills can be administered, but only with the doctor s advice.
Hot water fomentation over painful area during night, for better sleep.

Back Pain and Bad Sleep

Pain causes a lot of discomfort in the body no matter whether the pain is in the back, legs or in the head. Almost all people experience lower-back pain at some point in their lives, which can be extremely painful and can cause considerable annoyance. The first medical specialty that comes to mind for relief of lower-back pain is Orthopedics. The other two specialists that play a vital role in treating lower-back pain are the neurosurgeons and the physiatrists.

Pain in the Back
It is very difficult for the body to source the pain when it is deep and this pain could be due to infection, disease or injuries in the back, stomach and heart. It is even possible that the pain radiates to different places in the body. Often back pain is accompanied by body changes like redness, fever, neurological problems, heat, and changes in body functions and for that diagnosis of the back pain may be very severe. Patients suffering from lower-back pain and with symptoms that comprise of weakness in the foot or other symptoms of a neurologic insufficiency must definitely see a neurosurgeon.

Back pain that occurs due to reversible problems is known to vanish in a few hours or in a day. However, if it continues longer and is accompanied by body changes, then there are chances that the condition can become worse.

Lower Back Pain - 8 Signs When You Must Visit Your Doctor

The causes and symptoms of chronic lower back pain

Lower back pain is characterized by a feeling of pain around the lumbar region (curve of the back connecting the upper back and glutes- muscles in the buttock that are responsible for thigh movement) caused by muscle or ligament injury. The spinal area is most likely to be affected by lower pain as it may impair routine activities like walking and standing. Any lower back pain that lasts for more than ninety days can be considered as chronic.

Causes of lower back pain

There are plenty of causes for lower back pain. Anything that exposes the lumbar area of the spine to a level of stress beyond its capacity can cause lower back pain. These causes are-

1. Disorders of the discs

The spinal area in the lower back comprises of small bones called the vertebra, which are connected to each other by pieces of cartilage known as discs. These discs act as shock absorbers, and when exposed to excessive shock can cause the disc to bulge, resulting in herniated discs. Wear and tear of the discs can also occur.

2. Spinal stenosis

Spinal stenosis occurs when the area around the spine becomes narrow. It may affect the nerves surrounding the lower back, resulting in pain.

3. Wear and tear of the joints and ligaments

Normal wear and tear of the joints and ligaments cause difficulties in holding the spine in its proper position and this progresses with age. This may cause a vertebra to slide over another and affect the nerve endings, giving rise to pain.

Symptoms of lower back pain

The symptoms of lower back pain are usually a dull or excruciating pain in the lower back. It can also affect other parts of the body such as the hips and the legs. In case of severe pain, simple activities like walking, bending and sitting will be impaired.



The Causes and Symptoms of Chronic Lower Back Pain

One of the most common complaints of men and women is that of a back ache with lower back aches being the most common. Apart from an improper posture, this may be caused by old age, lifting heavy weights or an injury to the back. A consistent back ache can affect your daily life and make performing regular tasks uncomfortable. Luckily, it can be managed quite well with simple ayurvedic remedies.
According to Ayurveda, backaches are triggered by an excess of Vata dosha. Thus, the Ayurvedic remedies for a back ache aim at reducing the Vata dosha. Ayurvedic remedies are natural and have negligible side effects. 

For this reason, they can be prescribed to both children and adults. Some such remedies are:

Cut down on spices: One of the main characteristics of the Vata dosha is dryness. This can be caused by pungent spices such as wasabi and green or red chillies. The internal dryness caused by these spices can lead to constipation which in turn can be one of the causes of low back aches. Hence, if you suffer from a chronic backache that may or may not be accompanied by constipation, cut back on the spices and try eating food that is slightly blander.
Eat food before it gets cold: Eating cold food or cold drinks can also increase the Vata dosha levels in our body. Coldness creates congestion and constricts the internal organs while warm food allows the digestive and stool carrying channels to stay open. This allows for the easy expulsion of waste and reduces toxins in the body. Hence, opt for warm drinks like tea or coffee instead of soft drinks and juices and try to eat your food while it is hot.
Padahastasana or the standing forward fold pose: This yoga asana is very effective when it comes to treating back pain as it allows the Vata dosha to flow easily through the body. In doing this it opens up the digestive channels that may have been causing constipation and back pain. It also relieves problems associated with sciatica. To practise this asana begin by standing upright with your feet beside each other. While inhaling, lift your arms over your head till they touch your ears. Bend forward from your hips while exhaling and try to keep the back and your legs straight. Touch the floor or wrap your hands around your calves. Bring your head as close to the knees as possible and hold for 5   10 seconds. Inhale and the slowly roll your body upright again.

Back Pain - Ayurvedic Remedies for Managing 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.
