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.

Shoulder Pain: Causes, Diagnoses & Treatment

Vaginismus is a condition characterized by significant pain in the vagina generally during sexual intercourse. This pain occurs on penetration due to the contraction of the vaginal muscles.

Causes

The exact cause of Vaginismus is not exactly known to the doctors. But some researchers suggests that the pain might result from severe anxiety or illogical fears before sex.

Vaginismus can be primary or secondary depending on the concerned woman s previous sexual experiences. Vaginismus can be linked to an earlier sexually painful experience, sexual trauma or psychological factors. In some cases, the pain tends to exist without any direct physical cause. The causes of the pain might vary from women to women and might occur in some cases with only one specific partner and not with others.

Sometimes the pain might stem from underlying infections or any other underlying complications.

The symptoms of Vaginismus are as follows:

Severe pain during intercourse.

Severe pain during insertion of tampons or during any medical check-ups.

The following treatments can be useful to treat Vaginismus:

If the pain arises due to anxiety or fear, counselling sessions can help you to a remedy.

If the pain arises whenever something penetrates the vaginal walls, progressive desensitization can be useful to treat the pain. The process aims to loosen the vaginal muscles so that you don t experience any pain during sexual intercourse.

Kegel exercises (at least 20 of them) can help in the initial stage to relax the vaginal muscles. After you exercise for a few days, you should try inserting one finger inside your vagina while doing the exercises. Try doing it gently and if it still hurts, try doing it with a lubricating jelly. This continuous procedure will help in the contraction of the vaginal muscles which eventually relax.

Vaginismus - Things You Should Be Aware of 

The Hijama or Cupping Therapy is an ancient form of Alternative medicine that has long been practiced in Egypt, China, and few Middle Eastern countries. The cupping therapy work wonders to deal with problems ranging from body pain, skin lesions to inflammation. It also plays a significant role in improving the circulation and blood flow. But what is the Cupping Therapy and how does it work? In this article, we will discuss some important points related to the cupping therapy along with its merits.

What is a cupping therapy?
A Cupping Therapy is a non-invasive procedure that involves the use specially designed cups (made of silicone, bamboo, glass, or earthenware) placed on the target skin area to create a vacuum or a suction to help treat a particular health condition.

What happens in a cupping therapy?
The cupping therapy can be Dry or Wet

In both the types, before using the cup, the cupping therapist uses a flammable substance such as herbs or alcohol (placed inside the cup) and sets it on fire. With the fire slowly going off, the therapist carefully puts the hot cup in the target area of the skin in an inverted (upside down) position (for around 3 minutes). This is done to create a suction inside the cup triggering an expansion of the blood vessels. Alternatively, a rubber pump can also be used to create a suction.
In Wet cupping therapy, the steps involved in creating the first suction (generally a mild one) is identical to those used in Dry Cupping. However, in wet cupping, following the first suction, small incisions or scratches are made in the target skin area. During the second section, it is through these cuts that the elimination of the toxic or impure blood takes place.
Soon after the therapy, the cuts are well bandaged along with the application of medicated creams or lotions to ensure a fast healing sans any complications.
For better lubrication and movement of the cups, the therapist may apply a herbal or medicated oil to the skin.
Some people may also opt for Needle Cupping. As indicative of the name, needle cupping involves the use of Acupuncture needles (inserted into the skin over which the cups are then placed to carry out the suction and the subsequent therapy).
Merits of a cupping therapy

The cupping therapy is a nonsurgical therapy that can be used to treat many health complications such as high blood pressure, varicose veins, gynecological problems (including infertility), anemia, dermatological conditions (such as eczema and acne), fibromyalgia, migraines, arthritis, hemophilia, to name a few.
The cupping therapy ensures a better pain management.
It works wonders in the case of stress and anxiety.
The cupping therapy goes a long way to restore the balance between the three Doshas.
It comes with negligible side effects (light bruises, mild burns, or minor skin infections).

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 

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.
