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.

Shoulder pain can be a persistent dull and nagging sensation in the upper arm or shoulder area. It can be easily differentiated from neck pain as it is related to the movement of shoulders i.e. it will increase and decrease with shoulder movements, especially overhead activities. The other signs to identify shoulder pain is if your shoulder movements are reduced.

If you find it difficult to scratch / wash your back, comb your hair or reach your back pocket, it clearly shows you are suffering from shoulder pain. Shoulder pain can happen due to various reasons, it varies from person to person depending on the activities he/she is involved in, for e.g. sports, manual job etc. It can be a single major injury or multiple small injuries due to repetitive usage patterns. Also, degenerative changes in various parts of the shoulder can lead to shoulder pain.

In case of middle to old age, injuries that can cause shoulder pain are:

    Biceps Tendonitis
    Acromio-clavicular Joint arthritis
    Scapular Dyskinesia
    Trapezitis
    Suprascapular nerve entrapment In young age, injury due to sports or gym activity can cause shoulder pain
    Superior labral anterior/posterior (SLAP tear)lesion

Also, traumatic or repeated dislocations of shoulder can cause shoulder pain due to:

    Bankart lesion

Diagnose Shoulder Pain

Shoulder pain can be diagnosed only after thorough history taking and clinical examination. However, some imaging studies can be very helpful like:

    X-rays: Through an x-ray one can view the shoulder in many different views.
    Ultrasound: With an ultrasound, you can also check the damaged caused to the tendons and muscles of the shoulder but the quality of reporting depends upon the expertise of the doctor.
    MRI: MRI gives a clear picture of the shoulder as it shows everything related to a shoulder joint that is joints, vessels, tendons and muscles that too from different angles.
    Diagnostic Arthroscopy: A surgical procedure often used by orthopaedic surgeons to diagnose and treat issues inside a joint. Arthroscopy has the big advantage that one can use it to diagnose as well as treat at the same time.

Treatment for Various Types of Shoulder Pain

    For Shoulder Impingement or Rotator Cuff tear: Give rest to the shoulder for a few days only Dedicated Physiotherapy Protocol Bursal injections If these fail then, (Surgery)Arthroscopic sub-acromial decompression If Cuff tear is found, then one can go for Arthroscopic/Mini-open repair
    Labral Lesions: For anterior Labral lesions (Bankart's) following anterior shoulder dislocation then surgery in the form of Arthroscopic Bankart's repair is the only option to reduce risk of recurrence and degeneration.

SLAP Lesions

    Pain relief and physiotherapy as first step If this fails then following surgical options are available
    Arthroscopic debridement or repair of labrum
    Biceps tenotomy or tenodesis

Arthritis

In this case, the joint is already destroyed and has to be resurfaced for pain relief and to maintain ROM. If Rotator cuff muscles are working, then Shoulder resurfacing hemiarthroplasty (preferred in young people), that has a life of 10 to 15 years, Total shoulder replacement (preferred in middle aged to old people) has a life of 10 to 15 years. But, if rotator cuff muscle are not working then Reverse Geometry Shoulder replacement is recommended, that has a life of 10 years.

It is always advisable to get yourself diagnosed properly in case of shoulder pain as management changes depending on clinical situations. Neglecting shoulder conditions can lead to bigger problems later on.

6 Bodily Pains You Must Never Ever Ignore

In most cases, pain anywhere in the body can be explained as a symptom of some other problem, but sometimes, there is no reason for abdominal pain. This type of pain is known as chronic functional abdominal pain. This is a gastrointestinal disorder that cannot be explained through X-ray or laboratory findings. It can be triggered by altered sensitivity to nerve impulses in the brain and gut. People suffering from this condition are often so debilitated by the pain that it becomes the central focus of their life.

This condition cannot be cured, but with proper treatment, it can be managed so that it does not affect the quality of your life. The aim of treatment for this condition is to control the symptoms and improve functioning. When it comes to treating this condition, the patient s relationship with his or her doctor plays an important role as the condition cannot be proven through any form of testing and it has a great psychological effect on the person. Regular checkups are also a key to managing this condition effectively.

The first step towards achieving this is to identify possible emotional and situational triggers. Maintaining a journal that records these experiences can help with this. Further treatment is usually either through psychological treatment or antidepressants.

Psychological treatment is based on the understanding that the brain can block pain by diverting attention elsewhere. Nerve impulses that travel from the abdomen to the brain must pass through a type of  gate  that is controlled by nerve impulses generated by the brain. When these impulses close the gates, pain is blocked while when these gates are open, the pain can be magnified. Psychological treatment for chronic functional abdominal pain can be in the form of relaxation techniques, imagery, hypnosis and cognitive behavioral therapy. While relaxation techniques such as meditation and hypnosis help a person shift focus from the pain, cognitive behavioral therapy teaches a person how to change thoughts and perceptions in order to control the pain.

Antidepressants can also act as pain relievers. This form of medication stimulates the production of brain signals that close the  gates  of nerve transmissions. This blocks the pain but can take several weeks to be effective. Some people may experience side effects such as drowsiness and nausea and hence should never be taken without a doctor s supervision. In some cases, antidepressants may also be combined with cognitive behavioral therapy or medication to regulate bowels.

Ways to Treat Chronic Functional Abdominal 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.

Pain in Stiches - When You Should See Your Doctor?

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.
