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

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

Does you back hurt only when you wake up in the morning or is it a chronic problem? If yes, then you need to take immediate steps to treat it. Back pain, being the common physical anomaly for people primarily in the age range of 35-50, is one of the top causes for office absenteeism and mid-life lethargy and fatigue. Usually back pain indicates an underlying problem that involves the nerves, bones and muscles.

Here are some risk factors for back pain:

Pregnancy
Stress related to work
Leading a sedentary lifestyle
Anxiety and depression
Being overweight
Over exercising
Strenuous physical work outs
Smoking
There are varied reasons as to why back pain may occur. Discussing the causes of back pain is beyond the purview of this article; the focus is now going to be on some of the stretches one can practice to get relief from back pain: 

Downward dog: A classic yoga pose, the downward dog stretches the entire back, hamstrings and the whole of the leg. Begin the process in a classic push up pose with the palms and toes on the floor. Keeping your back straight, lift your tailbone up and straighten your legs. Push the heels to the floor and breathe to get the most out of this stretch.
Child s pose: A simple stretch, it begins with you sitting back on your buttocks and then stretching the arms in front of you. Keep your forehead on the floor and breathe slowly.
Cat cow pose: If your common complaint is that of a sore and painful back, then this is one of the best stretches for you. A very simple pose, you begin by sitting on all fours, then transitioning into the cat pose by pushing your spine upwards. Hold the pose for one breath and then go to the cow pose wherein you lift your buttocks and the head while scooping your spine.

Back Pain - 3 Stretch Exercises You Must Follow!

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.

When Should You See Your Doctor in Back Pain?

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.

10-minute easy exercises to relieve back pain

Most of us lead sedentary lifestyles these days which have led us to experience severe problems with our spine. Irrespective of your age, a majority of people today suffer from back pains as a result of sitting for long periods. The most effective way to counter back pain is to strengthen your spine to make it capable of dealing with these aches in a better manner.

You have to lie on your back and choose a firm and rigid surface. Start by lifting your legs slowly and avoid any bending. Keep lifting them to bring them at an angle of 90 degrees with your upper body and then return to the starting position. Around 15-20 repetitions of this exercise on a daily basis are bound to give you much relief from recurring back pain.

2. Cycling - this exercise is perfect for building coordination among all the abdominal muscles of your body. Set your body in a sit-up position with your back on the floor and knees bent. Next, move your legs in a pedalling position, as you would do in case of riding an actual bicycle. Continue the movement for about 20 seconds in each direction.

3. Plank positions - in a plank position, you are required to hold your body in a particular position for a specified time period. For example, you can perform a plank position by holding your body in a position that it would acquire during a push-up. Do not rest on your palms and instead bend them at your elbow, so that your weight now rests on the forearms. Breathe deeply and hold the position for a minimum of 30 seconds.
