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.

What you must know about body ache


Affecting your entire body, body ache is usually an indicator of a condition that requires your attention for the pain to stop or a reaction of your body's immune system to an infection. Understanding the symptoms and the cause of the pain is the first step towards getting the right treatment for your problem.
The causes of body ache can be any one of these:
  an increase in your body's lactic acid as a result of overused muscles (that you normally experience when you perform strenuous exercises) leads to body aches that are not severe but temporary in nature.
  temporary body aches can also occur if you suffer from flu caused by the influenza virus and other medical conditions like fever and viral infections, among others.
  a cause of body aches can be the presence of a serious condition such as Lyme disease or pneumonia that brings about major infection affecting your entire body.
  inflammation of body cells or damage to your body's nervous system in the form of chronic ailments like autoimmune diseases and psychiatric problems can also cause pains and aches to develop all over the body.

What can you do to manage it?
There are simple ways that you can employ to relieve your body aches based on the root cause and these are:

  if the cause of your body ache is the flu, the best way to alleviate your condition is to take a hot bath. The hot water works by eliminating the body pains you may be suffering from. Even a gentle massage can soothe the ache affecting your entire body.
  for body aches that are caused due to overused muscle, you need to apply ice packs for 2-3 weeks on the affected area to bring down the inflammation. Even the application of a heating pad can help in relieving body aches brought on by muscle soreness.
  shoulder and neck pains can be easily prevented by performing simple exercises from time to time such as shoulder shrugs or head turns. Also, the practice of using wrist and forearm rests can reduce your chances of getting shoulder and neck aches.
  reducing your stress levels can also help in effectively lowering the instances of body ache. From sleeping on time to meditating for about 20 minutes a day can help in lowering stress.

In case, you do not get relief from any of the suggested ways, you need to consult a qualified doctor who will guide you on the right treatment course.

Catagories of sutures

    Non-absorbable stitches: Such stitches are applied in case of skin wounds or internal wounds. Such stitches get healed quickly and are easy to remove. Non-absorbable stitches are made of natural fibers or synthetic threads like nylon polypropylene. As the name suggests, these stitches are either permanent or persist for a long time.
    Absorbable stitches: Such stitches are applied on layers, which have the property of healing quickly. They are very firm during the initial days. Then they start getting dissolved in the body.

Precautions taken by medical team before applying stitches to prevent infection

    Careful checking of nose for occurrence of germs before the start of operation.
    Skin must be cleansed prior to surgery.
    Sanitizing hands prior conducting the surgery.
    Usage of germ free gloves and sterile clothes while applying sutures.
    Prescribing antibiotics to the patients who may fear high risk of infection.

Precautions to be taken by patient to prevent infection

    Take a bath prior to surgery.
    Avoid using razor at the surgical site. The same can be carried out by using clippers by the surgery team itself.
    Keep all your jewellery aside before the operation starts. Do not apply nail polish.
    It is advised to cover up the wound. Try to keep the adjacent areas germ free. This is a crucial step in avoiding infection.
    Visit your doctor at once on finding redness around the wound.

When to see the doctor
Pain up to a certain threshold is normal. In case pain gets unbearable, the scene can be alarming. It may be an indication of infection. Taking immediate remedial steps is necessary to avoid infection or any other side effects post the surgery. On meeting with any of the following signs, it is better to consult doctor at once.

    If the skin around the wound gets swollen.
    If you detect redness around the wound.
    If the pain becomes unbearable.
    If the wound starts developing pus.
    If your body temperature increases abnormally or if you have fever.
    If you observe red streaks around the wound.
    If in case a stitch gets opened up and the edges of the suture start widening. This is the most alarming sign. In case a suture gets opened, you must immediately seek a remedy.

Avascular Necrosis, also termed as Ischemic Bone Necrosis or Osteonecrosis is a medical condition characterized by the bone death on being deprived of blood. The condition is known to occur in the shoulder, ankles, and knees. However, the part of the body most affected by Avascular Necrosis is the hip. In this article, we will describe the conditions that contribute towards Avascular Necrosis of the hip along with the associated symptoms.

Factors that lead to Avascular Necrosis of the hip
The supply of blood to the bones may be interrupted by a myriad of factors some of which include

1. Certain medical conditions and health disorders such as

Gaucher's disease: A genetic disorder resulting from glucocerebrosidase enzyme deficiency. As a result, glucocerebroside gets deposited in the cells of the macrophage-monocyte system.
Sickle cell anemia: A genetic disorder which results in the RBC's appearing like a sickle cell instead of being round shaped.
Both of these conditions bring about a significant reduction in the supply of blood to the bones resulting in Avascular Necrosis.

Certain inflammatory conditions that may damage the arteries and trigger Avascular Necrosis of the hip include autoimmune diseases, pancreatitis or HIV infection.

2. Extensive and prolonged use of corticosteroids: Often used as non-inflammatory drugs, corticosteroids can play a contributing role, resulting in Avascular Necrosis (non-traumatic). The fatty substances are usually broken down by the body. However, the use of corticosteroids may affect this breakdown as a result of which the fatty substances start piling up in the blood vessels, constricting their size. The constricted blood vessels, in turn, reduces the supply of blood to the bones to a great extent.

3. An injury or a fracture affecting the femur: A hip fracture or a dislocation that affects the upper half of the thigh bone or the femur acts as a potential threat, triggering a traumatic Avascular Necrosis (AVN) of the hip.

In some case, radiation therapy or chemotherapy for cancer can go a long way in interfering with the ability of the bone (weakens the bone) to receive blood, causing bone death.

People who are into heavy drinking stand a greater risk of suffering from AVN. An increased consumption of alcohol causing constriction and narrowing of the blood vessels interfering with the flow of blood to the bones.

Symptoms characteristic of AVN of the hip

Unfortunately, the initial stages of AVN are asymptomatic. However, as the condition progresses into later stages, a person may experience pain and discomfort, particularly while exerting pressure on the bone affected by the condition.
As the bone and the adjacent joints deteriorate and collapse further, a person may experience great difficulty in using the joint altogether.
In some cases, the condition may progress and affect both the hips (Avascular Necrosis Bilateral).

Causes and Symptoms of Avascular Necrosis of the Hip

Pain management is an issue that stares back at mankind, irrespective of the underlying health condition. Whether it is a headache or a back pain, burn or fracture, heart attack or cancer, pain is always a symptom. In some cases like migraines, cancer, etc., the pain is chronic and the patient needs to be constantly on the vigil to know when an attack will ensue. This has also put high pressure on the medical fraternity to identify ways that can provide relief to these people. Various methods have been identified, and one of them is the electrotherapy.

What is done?
A few electrical impulses are directed at the area of the pain using a hand-held device. This is similar to providing electric shocks of mild intensity to the affected area (forehead, low back, neck, etc.). What this does is stimulate the nerve endings, improves circulation and muscle strength and promotes bone growth and tissue repair. The end result of all this is overall improved functioning and pain relief. Depending on the actual condition, the sessions will have to be repeated. In some patients, the electrotherapy is used in conjunction with other therapy so that they can go about their routine exercise and pain relief.
The sessions may also have to be repeated as most often these are used in individuals with chronic pain. They are also helpful in providing relief during the acute attacks.

How does it work?
The most common form of electrotherapy is known as TENS, which stands for transcutaneous electrical nerve stimulation. The area to be treated is cleansed with spirit and then small sticky pads are applied through which the electricity is passed. A hand-held device is used, through which electrical impulses are passed to the skin, which stimulates the nerve cells to provide relief from pain. It causes a vibrating and tingling sensation in the treated area. It is believed that it blocks the nerve impulses and therefore provides pain relief. Another theory states that they promote the release of endorphins which are natural painkillers; it is also very effective in case of migraine and sciatica and neck pain where the chronic pain is coupled with acute spurts.

With narcotic painkillers having various side effects, techniques like electrotherapy are gaining popularity. A small catch also is that it does not work for everybody and in most people with back pain, fibromyalgia, and migraines, requires repeat sessions for relief. The cost of each session also needs to be considered against the extent of relief achieved. However, for those whom it works, it is a very good technique for chronic pain control.
