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 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.

Electrotherapy - How It Can Help In Managing Pain?

Stitches or sutures act as a closure for either surface wounds or deep wounds. Procedure to close a deep wound comprises of sewing the two edges and applying stitches under the skin surface.

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.

Ask your doctor for the precautions you can take to avoid experiencing any of the above signs. If you come across such alarming symptoms, rush to the nearest hospital and get the appropriate treatment.

This could be much more crucial than just a problem with the digestive system.

Many cases that doctors come across when a patient comes to consult about a pain in the neck are regarding an issue with the spinal cord. At in certain cases, it could be related to an issue with the muscles which are located in the area.

When a person has neck pain, he or she should think back and try to remember if he or she was in an incident where the neck could have possibly been the recipient of some sort of impact. This could be a possible explanation of the pain. Also, if there is a pain in the neck after an incident, it is better not to delay a visit to the doctor as the person is likely to be uncomfortable. The neglect is this condition can also lead to the problem getting progressively worse.

In some cases, a pain in the neck can even be congenital. A very good example of this is wry neck, or torticollis. When a pain in the neck is diagnosed by the doctor, figuring out what the likely cause is quite an important thing to do and should be the first thing which is done by him or her as the various ways to treat a pain in the neck vary according to the cause of it.

The problem of neck pain is very common as two third of the population suffers from it at some point in their lives. This does not mean that it needs to affect a person's quality of life. The right precautions and proper medication can make sure that his or her neck is not on the line!

Causes of Neck Pain and Diagnosis

The Anterior cruciate ligament (ACL) is an important ligament that gives stability to the knees. An injury to this ligament can result in a host of complications and discomfort. Children or adults who are into sports such as gymnastics, volleyball, tennis, basketball, soccer, football, often injure this ligament. As per various studies and surveys, ACL injury is more likely to affect female athletes as compared to their male counterparts.

Depending on the severity and extent of the damage, an Anterior Cruciate Ligament Injury may be ranked on a grade of 3.

Grade 1 sprains indicate a mild injury or stretching of the ligament, seldom affecting the stability of the knees.
Grade 2 sprains are indicative of a partial ligament tear (the ligament loosen up). The damage is still under control.
Grade 3 sprains are extensive and severe, indicating a complete ligament tear (the ligament often breaks in two pieces). With a complete ligament tear, the stability of the knee is also affected (the knee becomes highly unstable).
What causes Anterior Cruciate Ligament (ACL) Injury?
While a host of sports activities mentioned above increases the risk of the injury, a person may also suffer a partial or a complete anterior cruciate ligament tear under the following situations.

A jump down a ladder, a tree, or a wall. An incorrect jump or a landing may be equally responsible for the ligament tear.
A collision or a hit, especially on the knee (while playing football).
Slowing down suddenly while still in running motion. A person suddenly stopping or missing a step can also injure the ligament.
Symptoms associated with ACL injury

An excruciating pain (especially in the back and outside of the knee) is often seen in people with a complete ligament tear (the movement is yet not affected). However, within a few hours, there may a swelling around the knee, indicating the severity of the injury with internal bleeding within the knee joints.
There may be restricted knee movement. The knee also feels unstable, further limiting the movement.
Sometimes a pop in the knee can be heard just at the time of the ACL injury.
Prolonged ACL injury left unattended can result in a painful complication such as knee osteoarthritis.
Diagnosis
To diagnose the extent of the damage, the doctor may suggest

Physical examination, including a quick brief about the case history.
Imaging tests such as X-rays and MRI can go a long way to analyze the ligament injury.
In the case of extensive swelling of the knees, the doctor may carry out an arthroscopy to have a closer look inside of the knee.
An accurate and timely diagnosis is important to avoid the aggravation of the injury. In the case of swelling and knee pain, consult a doctor, and get yourself thoroughly examined.
