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.

Hot and Cold therapy is one of the most popular home remedies for any kind of joint pain or muscle sprain. In some cases applying heat therapy and cold therapy alternatively, can help relieve the pain while for others only one form of therapy is necessary. To understand what to use when, one should first understand the effect of heat and cooling on the body.

Applying a heat pack or immersing the affected limb in hot water improves blood circulation and makes the muscles more flexible. Thus, it can help relax a muscle and fasten the healing of damaged tissues. On the other hand, cold therapy or cryotherapy reduces blood flow to the affected site. This helps relieve inflammation and pain caused by it. It can also make the area feel numb by reducing nerve activity temporarily.

Types of Heat Therapy
Heat therapy can be categorized as dry heat and moist heat. Dry heat involves using saunas or dry heating packs to relieve pain. This is also known as conducted heat therapy. As the name suggests, moist heat involves the use of steamed towels, hot baths and moist heating packs. This is also known as convection heat therapy. Moist heat is usually considered more effective than dry heat.

Types of Cold Therapy
Cold therapy may be applied to a part of the body or to the entire body. This includes ice packs, coolant sprays, ice baths, ice massages and whole body, cold therapy chambers.

How to use heat and cold therapy?
The sooner heat and cold therapy is given to a person, the faster they will recover from their pains. Heat therapy can be given to a person for extended periods of time but when giving cold therapy, a person should not be exposed to a cold pack or ice bath for more than 10-15 minutes. Care should also be taken no to apply ice or a frozen pack directly on the skin as it can damage the skin and nerves.

When not to use Heat Therapy?
If the injury site is swollen or bruised, cold therapy is better than heat therapy. Heat therapy should also not be applied to an open wound. People suffering from conditions such as diabetes, dermatitis, deep vein thrombosis, vascular diseases and multiple sclerosis should also avoid heat therapy as these conditions can increase the risk of burns and other such complications. Pregnant women should also consult a doctor before using a hot tub or sauna.

When not to use Cold Therapy?
Cold therapy is avoidable for treating stiff joints and muscles. People suffering from poor circulation and sensory disorders should also avoid using cold therapy without a doctor s supervision. 

Hot & Cold Therapy - How It Can Treat 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.

Are you prone to slipped disc problem? + the ideal way to treat it

A slipped disc, also known as a prolapsed disc or herniated disc, is the term given to the phenomenon that occurs when a cartilaginous disc found between the vertebrae in the spine becomes slightly displaced or protrudes, thereby pressing on the nerves in the adjacent areas and causing back pain.
This happens when the soft inner part of the disc, known as nucleus pulposus, bulges out through a weakness in the exterior part of the disc. A prolapsed disc usually occurs in the lower region of the spine and can be of varying sizes. There might even be the development of inflammation around the disc in some cases.

Who is likely to get affected?
Most cases of herniated disc occur in patients between the ages of 30 and 50. The number of men affected is twice as many as the number of women.
Although the root cause of this problem is not yet known, there are a number of factors that may trigger it. These factors include working at a job that requires a lot of lifting, an occupation that involves remaining in a seated position for a long time, weight-bearing sports, obesity, smoking habits and increasing age.

Effective ways of treating the problem
The different methods that are commonly used to treat the problem are:
Medications
There are many different kinds of medicines that are effective in providing relief. These include painkillers, muscles relaxants, anti-inflammatory pills, etc.

Spinal injections
A number of spinal injections are used to treat slipped discs. The injection is done at the opening where the inflamed nerve roots are found and reduces pain, swelling and irritation in the area.

Radiofrequency ablation
This procedure makes use of an electrical current produced by radio waves to reduced pain and sensitivity in the affected area.

Ozone discectomy
As opposed to the surgical removal of the prolapsed disc, this new process makes use of an ozone-oxygen mixture that is injected into the spine to treat the problem. Many international studies have proved its superiority to traditional methods and surgeries.

Those affected by this problem are advised to keep exercising and continuing with their everyday activities as best as possible.

6 Bodily Pains You Must Never Ever Ignore

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.
