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

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.

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.

How To Control Nerve Pain?
Nerve pain or peripheral neuropathy, as it is medically known, is characterized by pain, numbness and weakness that arise out of nerve damage. This pain is usually restricted to the feet and the hands.
What are the common causes?
Diabetes is the most common cause for this condition. However, other causes, such as injuries, infections and prolonged exposure to certain toxins can also trigger nerve pain.
How can you control nerve pain?
Nerve pain can be managed and taken care of at home taking into consideration the points that have been mentioned below:
Topical Painkillers: Certain over the counter ointments and creams can help relieve nerve pain. These medications act as local anesthetics; that is they numb the area of the pain. Capsaicin, a derivative of chili peppers, is one of the major ingredients used in these medicines. Others use botanical oils as the major ingredients.
Painkillers: There are painkillers available OTC which can curb nerve pain. However, painkillers such as ibuprofen, aspirin and acetaminophen do not really work well for severe pain of the nerves.
Supplements: The lack of Vitamin B12 is considered to be a very important cause, and at times, a catalyst for nerve pain. In a case such as this, Vitamin B12 supplements or injections might be administered. Although more research needs to go into this, but certain supplements, especially gamma-linolenic and alpha-lipoic acid can help soothe nerve pain caused by diabetes.
Acupuncture: This time honored Chinese approach is a proven alleviator of nerve pain. Acupuncture releases chemicals which numb the pain, or prevent the pain signals from travelling to the brain.
Physical Therapy and Massages: Physical Therapy can especially heal and strengthen weak muscles that can stem from acute nerve damage and pain. Though more evidence is needed, according to a few sufferers of this condition, massages can be helpful with the tremendously painful muscle spasms that can so often result from nerve pain.
Relaxation Techniques: In combination with the above mentioned approaches, relaxation techniques can go a long way in relieving debilitating neural pain. Besides being helpful with dealing and reducing a few stress phases of life which can cause nerve pain, these techniques might actually root out the actual pain itself.
Lifestyle Modifications: This one s always a winner! Eating a well-balanced diet that guarantees all nutrients in uniform amounts can never go wrong. Regular exercises for about 30-45 minutes can remedy different types of pain; nerve pain being one of them. Try and limit alcohol intake (a peg once a week won t harm one, but binge drinking can play the ultimate spoilsport and make all health plans go topsy-turvy!). Abstain from smoking or chewing tobacco as this is usually the primary contributor towards any medical condition or disorder.

Nerve Pain - 7 Ways You Can Control it 

Prevention of leprosy: Leprosy is caused by the bacterial infection of Mycobacterium leprae and it is classified into multiple types. Leprosy is communicable through contact with common objects or a person by infected droplets within their nose. It primarily affects mucous membranes and the skin and the nerves on the hands, feet, and in extreme cases may cause disfigurement as well. There are no specific ways to prevent leprosy as no specific correlation between transmission and development has been found so far. Leprosy can happen through one time contact or through contact over extended period of time within the same household. Thus preventive measures will primarily include the following:

Regular checkups by going to the doctor
Ensuring that surfaces are kept clean if you share a household with a leprosy patient
Skin biopsies at regular intervals just to check if you may have contracted the bacteria
If a rash has developed, then it is urgent that you visit the doctor. Earlier the leprosy is detected, quickly it can treated and resolved
Incidences of leprosy have reduced over the last few decades due to improvements in medicine and early detection. This has allowed people to nip the problem in the bud and does not allow it to spread within their bodies or to other people.

Treatment of leprosy: The primary weapon that modern medicine has against leprosy is known as MDT or multidrug therapy. Multidrug therapy is the combination of multiple drugs, which attack the various aspects of leprosy, such as skin problems, nerve damage, loss of sensation, deterioration of skin conditions etc. This is the proven way to not only reduce symptoms, but also cure the problems in the long run.

Some of the drugs in the MDT used are as follows:

Rifampicin and dapsone
Rifampicin and clofazimine and dapsone
Rifampicin, minocycline and ofloxacin
However, the combination will depend on the type of leprosy the person is affected with, such as paucibacillary leprosy or multibacillary leprosy and thus can only be prescribed by the doctor after the thorough and detailed examination.

Leprosy - Treatment And Prevention!

Problems with the arteries and veins present in the hands or legs can lead to vascular disorders. The arteries carry blood from the heart to other parts of the body in order to deliver nutrients and oxygen. The veins carry the blood back to the heart, after the nutrients have been used up. If these blood vessels of the arteries or veins become blocked or narrowed, it can lead to a vascular blockage.

A vascular blockage that occurs in the hands or legs comes under the category of Peripheral Artery Disease or PAD. These type of disorders are less common in the upper extremities of the arms or hands than in the lower extremities of legs. Few of the signs for the same are:

Pain and difficulty in movement due to decreased blood flow
Numbness or weakness of leg or fingertips
Sores on the toes or feet
If the blockage is deep, symptoms of redness, swelling, extreme pain or cramping can be experienced
Abnormal color changes in the fingertips
Ulcers or wounds that don t heal
Skin sensitivity problems when in cold temperatures
How can it be diagnosed?
The blockage can be detected by various methods namely-

Physical Examination   Your doctor may find decreased pulse at armpit, wrist or fingers, full veins, masses, wounds or gangrene.
Doppler or Ultrasound examination to determine the blood flow in the arteries and veins
MRI Scan of the affected area to pay special attention to the blood vessels
Cold Stress Test
Arteriography to show clear blood vessel details
Angiography to map blockages and narrowing of the arteries
What are the Risk Factors for Peripheral Artery Disease?
An individual is at risk for developing vascular blockages in the hands or legs if one or more of the following factors are present:

Smoking
Diabetes
Heredity Factors   A personal or family history of blood vessel disease
High blood pressure
High cholesterol
Aging   People aged above 50 years and older are more prone to vascular blockage
Can it be treated?
Treatments for vascular blockage can vary depending on the age, cause of the blockage, intensity and overall well-being.

Treatments can include:

Self-care   Reducing risk factors and making lifestyle changes to quit smoking, sedentary life or diabetes, blood pressure and cholesterol management can reverse symptoms of vascular disease.
Medications   A variety of drugs can be prescribed to lower the risk and progression of narrowing blood vessels or prevent blood clotting.
Interventional Procedures   Minimally invasive surgery like saloon angioplasty, stenting or removal of artery plaque build-up.
Surgery   If the blockage is severe, surgery may be performed to lessen the vessel narrowing, reconstruct the artery or tie it off, depending on the circumstances.
