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.

When is your pain chronic?

Your pain is chronic if it last for more than a period of six months. Chronic pain is a long-term pain whose nature can vary from mild to excruciating, and it may trouble you either continuously or at short and regular intervals. Chronic pain is so dangerous that it does not only cause discomfort and inconvenience but also robs you entirely of your capacity to work for a long time.

Chronic pain can occur in a number of organs of the human body like head, joints, back, shoulders, neck etc. In fact, pain in any part of your body can turn into chronic pain. Here are a few symptoms that can help you identify if what you are going through is, in fact, chronic pain:

- persistent and severe body pain

- burning sensation accompanied by the body pain

- fatigue and sleeplessness

- weak immune system

- stiff and sore joints

The 4 types of chronic pain disorders that you should be aware of are:

1. Nociceptive pain

The pain that affects the soft tissues of the body such as the skin and the muscles or the organs that have sensory nerves present in them is called nociceptive pain. The sensory nerves, known as nociceptors can detect the stimuli of pain and send information to the brain and the spinal cord for interpretation. The pain could be either somatic (originating in the outer body) or visceral (originating in the internal organs).

2. Neuropathic pain

This pain is caused when the nerves stop functioning normally. It is caused due to nerve disturbances that result in pain stimuli being spontaneously transmitted to the brain and spinal cord. If you are suffering from this type of chronic pain disorder, you will feel a sharp, shooting and stabbing pain. Neuropathic pain can also be caused due to the formation of neuroma (abnormal growth of the nerve tissue).

3. Psychogenic pain

The pain that is caused by psychological disorders like depression and anxiety is known as psychogenic pain. Sometimes this pain can be accompanied by physical complications like fatigue, body pain and muscle weakness.

4. Idiopathic pain

The pain that exists even though there is no physical or psychological cause for it is known as idiopathic pain. This pain is more common in people who have suffered from a pre-existing painful disorder. Some common examples of idiopathic pain are fibromyalgia (intense pain all over the body) and tmj disorders (pain in the jaw area).

Your Pain is Chronic if it Falls Under These 4 Types of Chronic Pain Disorders!

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

International Childhood Cancer Day is celebrated annually on 15 February to raise awareness and to express support for children and adolescents with cancer, survivors and their families.

Why is Cancer the biggest Threat to the YOUNG in India?

There are fewer Indians who have successfully battled Cancer and have emerged successful. Yuvraj Singh, the legendary cricketer, who was diagnosed with a rare cancer at 29, survived due to an early detection. Cancer cases in India are not as many as they are in the developed world. However, due to late detection the survival rate in the country is far worse. Particularly, we are losing our youth to Cancer. Most tobacco (pan masala) related cancers and child cancers go undetected until very late.

Few cancers like cervical cancer and breast cancer which affect women of any age, are curable, however, due to lack of awareness and timely screening, many Indian women succumb to these cancers. The most common sites for cancer among men are lung, prostate, colon, rectum, stomach and liver while that among women are breast, colon, rectum, lung, cervix and stomach.

In proportion to our population, we lack the right infrastructure nationwide. esp in the northern and north eastern region, there is a dearth of good cancer facilities, where radiation, care or treatment can be given. Not even one third of cancer patients are alive beyond 5 years after their diagnosis in India, and about 71% of cancer deaths occur in patients in their prime productive years   between the ages of 30 to 69 years.

 Most Indians believe that cancer is generally incurable and that it should be kept secret from neighbors and family.  -  Dr Paul Goss, MD, Harvard University.

All these factors have contributed to a very high mortality rate. No wonder Cancer is dreaded in the country. Investment, infrastructure, lifestyles as well as mindsets need to change if we were to contain the Cancer mortality rate. While you need to watch out for early signs of cancer, here are the lifestyle changes every individual esp. all youth must adopt to avoid cancer.

Avoid Tobacco - both smoking and chewing.

Reduce alcohol intake - Save your organs from deteriorating.

Limit UV ray exposure from the sun - Keeps your skin safe.

Maintain a healthy diet - Include foods rich in Vitamins, minerals and fiber which nourish your body and build immunity.

Increase your level of fitness - Maintain a good bodyweight. Additional flab invites a host of troubles, that includes variety of cancers.

Seeking regular medical checkup or screening - This is the only way to prevent and get detected early on.

International Childhood Cancer Day - Why Cancer Is A Threat For Young?

Pelvic pain is most common in women, though sometimes it occurs in men as well. There is absolutely no reason why pelvic pain cannot be treated and therefore women need not panic if they are experiencing such pain. The treatment of any pain can be done methodically after discovering its cause. Thus, before jotting down the treatments for pelvic pain, it is important to explore the reasons that cause pelvic pain in women.

Reasons for pelvic pain

Reproductive organs in women play an important part in causing pelvic pain. The reproductive organ is complex when it comes to women and many small or big problems there might end up leading to pelvic pain.
Any urinary infection or bladder irritation might also lead to pelvic pain.
The nerves and muscles of the abdomen may cause pain in the pelvis area as well. In fact, the nerves and muscles are very tender near the pelvis area and care should be taken so that one does not strain them or pull the ligaments. This can cause severe pain.
Another interesting point to be noted is that sometimes even after going through a lot of examinations, no causes of pelvic pain are found. In such cases it is understood that the pelvic pain is a manifestation of the remains of a long forgotten injury or accident.
It has been examined and found out that physical abuse can at times lead to chronic pelvic pain. Though this link has not yet been understood properly, but it is seen to be true.
Treatments for pelvic pain

The most basic treatment is to apply heating pad on the affected area. Heat helps in relaxing the muscles and nerves thereby, lessening the pain. However, this would reduce the pain, but cannot make it disappear in a day. Thus, it is a continued process for a week or 10 days till the pain recedes.
Relaxation techniques like meditation, breathing exercises, yoga and even muscle exercises like jogging help in reducing the pain. However, this should be done under guidance. One wrong move can actually aggravate the pain instead of lessening it.
Then there are painkillers which are non-steroidal and help in lessening the pain. Painkillers have a correct dosage and must be taken only after consulting a doctor. Self-medication in such cases can prove disastrous.
At times, when all medications fail, surgery is the last resort.
Thus, these are some of the treatments that can be undertaken if and when you are experiencing pelvic pain. All these are connected to the root cause and must be followed only under medical supervision.

Pelvic Pain - 4 Ways It Can be Treated

Pelvic pain is generally referred to as the pain in the lower abdominal region. Pelvic pain might be acute, sudden, or chronic, recurrent, cyclical in nature. It may present as central or lateralized pain and might spread to the thighs and buttocks. Pelvic pain might be an indication that something is wrong with the internal reproductive organs located in the pelvic region such as ovaries, fallopian tube, uterus and vagina in which case occurrence of pain may be related to particular time in menstrual cycle.

Pelvic pain can be indicative of a pelvic infection or related to the pelvic bones/spine problems.

Also it may indicate that there is something wrong with the digestive system or urinary system.

Causes-

The causes are as follows:

Pelvic pain occurs commonly in disorders of the internal reproductive organs such as ovarian cysts or pelvic inflammatory disease (where in sexually transmitted bacteria spread through the reproductive organs and cause infection) or pain during ovulation.

Pelvic pain might also occur due to endometriosis (a form of disorder where the endometrial tissues that are located inside the uterus tend to grow outside the uterus resulting in severe pain), adenomyosis (a disorder wherein the endometrial tissues which line the wall of the uterus tend to grow within the uterus), , pelvic adhesions or ectopic pregnancy (when the fertilized egg gets inserted somewhere else other than the main uterine cavity),

Pelvic pain can occur due to bladder disorders, kidney stones, infection in the urinary tract, constipation, flatulence,inflammatory bowel disease, irritable bowel syndrome and chronic hernia.

It can also be a symptom in some cancers such as ovarian cancer, colonic cancer, advanced ovarian , endometrial and cervical cancer.

The following symptoms might occur along with pelvic pain:

Sustained pain in the hips and the groin

Sudden fever

Severe pain while urinating , passing stools or during sexual intercourse (dysparuenia)

Vaginal bleeding or vaginal discharge .

Blood in stool

Severe menstrual pain ( dysmenorrhoea)

Repeated instances of constipation or diarrhoea

Increase In pain with stress and physical movements

Investigations-

The Gynaecologist will do physical examination including bimanual internal examination. Also, complete blood count, urine for microscopy, vaginal swabs if discharge, stool examination. Ultrasound examination of the pelvis is an important investigation.

Treatment-

If the pain is gynaecological and depending on the cause doctors might suggest different therapies. In cases where pain is due to an ovarian cyst or endometriosis, doctors may prescribe birth-control pills. In cases of suspected pelvic infection, antibiotics are prescribed. Also, laparoscopic surgery might be advised in cases of acute pain due to cyst, endometriosis, or pelvic adhesions: for confirmation of diagnosis and excision or removal of cysts and endometriotic implants and division of adhesions respectively. In some cases of chronic pain, the gynaecologist may manage the case with inputs from gastroenterologist and pain consultant.
