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

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

Avascular Necrosis, also termed as Ischemic Bone Necrosis or Osteonecrosis is a medical condition characterized by the bone death on being deprived of blood. The condition is known to occur in the shoulder, ankles, and knees. However, the part of the body most affected by Avascular Necrosis is the hip. In this article, we will describe the conditions that contribute towards Avascular Necrosis of the hip along with the associated symptoms.

Factors that lead to Avascular Necrosis of the hip
The supply of blood to the bones may be interrupted by a myriad of factors some of which include

1. Certain medical conditions and health disorders such as

Gaucher's disease: A genetic disorder resulting from glucocerebrosidase enzyme deficiency. As a result, glucocerebroside gets deposited in the cells of the macrophage-monocyte system.
Sickle cell anemia: A genetic disorder which results in the RBC's appearing like a sickle cell instead of being round shaped.
Both of these conditions bring about a significant reduction in the supply of blood to the bones resulting in Avascular Necrosis.

Certain inflammatory conditions that may damage the arteries and trigger Avascular Necrosis of the hip include autoimmune diseases, pancreatitis or HIV infection.

2. Extensive and prolonged use of corticosteroids: Often used as non-inflammatory drugs, corticosteroids can play a contributing role, resulting in Avascular Necrosis (non-traumatic). The fatty substances are usually broken down by the body. However, the use of corticosteroids may affect this breakdown as a result of which the fatty substances start piling up in the blood vessels, constricting their size. The constricted blood vessels, in turn, reduces the supply of blood to the bones to a great extent.

3. An injury or a fracture affecting the femur: A hip fracture or a dislocation that affects the upper half of the thigh bone or the femur acts as a potential threat, triggering a traumatic Avascular Necrosis (AVN) of the hip.

In some case, radiation therapy or chemotherapy for cancer can go a long way in interfering with the ability of the bone (weakens the bone) to receive blood, causing bone death.

People who are into heavy drinking stand a greater risk of suffering from AVN. An increased consumption of alcohol causing constriction and narrowing of the blood vessels interfering with the flow of blood to the bones.

Symptoms characteristic of AVN of the hip

Unfortunately, the initial stages of AVN are asymptomatic. However, as the condition progresses into later stages, a person may experience pain and discomfort, particularly while exerting pressure on the bone affected by the condition.
As the bone and the adjacent joints deteriorate and collapse further, a person may experience great difficulty in using the joint altogether.
In some cases, the condition may progress and affect both the hips (Avascular Necrosis Bilateral).

Causes and Symptoms of Avascular Necrosis of the Hip

There are many ways to treat pain and this includes acupuncture, several natural remedies, technological procedures and surgery. Among the different approaches for treating pain, massage therapy is an effective method.

Massage therapy is one of the earliest therapeutic processes for relieving pain for a long time as it provides ideal relief and performs recovery functions as well. In the modern day, massage therapy is a popular pain relieving remedy, which is utilized by people all over the world.
Massage therapy involves manipulation of the tissues, which is performed by special therapists. There are various types of massage therapies, which incorporate different techniques and procedures.
Long-term massage therapy is not very expensive and has no side effects on the body. With the help of massaging, there is an increased lymph flow, improved blood circulation and several positive effects on the immune system. 
Conflicting views

The current studies on massage therapy are quite conflicting and there are negative views regarding the effects of massage therapy to provide pain relief. Massage therapies are successful in treating several cases of lower-back pain. However, many experts consider massage therapy to be a relaxation technique and not a proper treatment procedure.

They say that massage provides relief to pain, but physical therapy, exercise and medicines are far superior in providing pain relief than massage therapy. Massage provides relief to neck pain, shoulder pain, headaches and carpal tunnel syndrome. However, it is considered that this relief is only temporary and not consistent enough. A single session of massage therapy does not really provide a long-term relief from pain. For better and lasting results, massage therapy should be undertaken regularly.

Multidisciplinary treatment

Massage alone will never provide ideal relief from any kind of pain and a multidisciplinary approach should be taken for pain relief treatment, where massage therapy would be one of the elements. For ideal pain relief, you should practice other measures such as physical therapy, behavioral health care, acupuncture, regular exercise and use massage therapy as a complementary relief method.

Massage therapy can never be the main treatment procedure for treating pain and it is an accompanying treatment method which you should practice along with major treatment procedures. Massage therapy combined with other therapies will provide you effective pain relief.

Massage therapy for pain provides effective temporary relief from pain. It should be performed by a trained massage therapist and for good results must be performed every day. However, massage therapy is not a primary treatment measure and should be a part of a multidisciplinary approach for pain relief.

Massage Therapy for Pain - An In-Depth Analysis!

Acupuncture is a kind of therapy that combines needles with pressure and pain points in order to delicately apply pressure for pain relief. This form of physical therapy is being increasingly recognised as an efficient method of treating pain in joints, muscles, bones and even for migraine pain. So let us find out more about Acupuncture and pain management.

    Chronic or Long Term Pain: There are many ailments that cause chronic or long term pain. These include back pain, neck pain, stiffness in the joints, osteoarthritis, headache and migraine, and pain in the shoulders. All this can be treated over a long period of time with the help of simulated acupuncture which uses pointed apparatus for activating better blood circulation for overall improvement in the pain that is being experienced in the area. The use of this apparatus helps in avoiding the harmful medication that can have adverse side effects.
    Menstrual Cramps: A fine needle method at the right points can help in bringing down the symptoms of the painful condition called dysmenorrhoea during menstrual cycles. With acupuncture, the acupuncturist can administer acupoint therapy to relieve menstrual cramps. This will help in moving the qi, or life force, in a better way so that the pain will stop. 
    Acute Pain: Over use of muscles, joints and repetitive, work related movements and strain can lead to acute pain. This includes wrist pain, shoulder pain, elbow pain, back pain, lower back pain, neck pain and even leg pain. With acupuncture, the patient gets rid of the pain in close to twelve sittings.
    Pain due to Cancer Treatment: Cancer and its treatment can take a heavy toll on the body and lead to a series of complications which also includes pain. A clean needle procedure can be followed along with the chemotherapy and radiation or after it, so as to relieve the patient of the pain experienced. Also, it can be used to replace traditional chemotherapy and radiation. 
    Better Rest: When the needles or apparatus touch the pressure points and circulate the blood and life force, it actually creates a soothing effect and helps the patient sleep and get better rest. This is also a requirement for pain relief. It can bring better blood flow to the area and help in removing anxiety and stress related to pain so that there is better chance of getting rest. 

With the use of acupuncture, pain can be taken care of with the needles and various tools that come in various shapes. These tools and equipment can also use laser treatment along with the point focused treatment.

Acupuncture and Pain Management

Hemorrhoids or piles are diagnosed by swelling of veins in the lower part of anus and rectum. Due to swelling, the walls of rectum and anus are stretched and thus become irritated. Hemorrhoids are of two types: Internal and External hemorrhoids.

Internal Haemorrhoids: As the name suggests, the piles are not visible from outside. These are present deep inside the rectum, located above the pectinate line and these are covered with the cells that are present through the rest of intestines. Internal hemorrhoids are normally painless. The first sign of internal hemorrhoids is rectal bleeding. However, straining can push internalhemorrhoid and it protrudes through the anus and this can be painful.

Causes of Haemorrhoids
The swelling of hemorrhoid occurs only when the pressure in the small vessels of rectum and anus is increased and is engorged with blood. The size of the hemorrhoids is also increased. The increased pressure may be due to various factors:

Consuming low fiber diet and pushing or straining while passing stools, thus blood vessel pressure is increased.
Pregnancy also is a cause of swelling as there is the increased pressure of the uterus on rectum and anus.
Sitting for long on toilet also increases pressure.
Obesity is also a cause of hemorrhoids.
People suffering from diarrhea, both acute and chronic.
A person having colon cancer might have hemorrhoids.
Signs and Symptoms of Haemorrhoids:

The most common symptoms of hemorrhoids are painless bleeding, itching in anal, swelling and feeling of the presence of lump at the anus.
All these symptoms are associated with inflamed hemorrhoid.
Inflamed internal hemorrhoid can cause swelling, but is painless as there are no fibers attached to veins above the pectinate line that cause pain. However, passing hard stools can scrape off the thin lining of hemorrhoid, which can cause the painless bleeding.
Spasms of the rectum and anal muscles caused by these swollen hemorrhoidscause pain, especially when they are protruded through the anus.
Internal hemorrhoids can form a clot or thrombose resulting in severe pain.
The presence of has inflammation, stool,and constant moisture and these can lead to itching and burning sensation in the anus among patient of internal hemorrhoid.
Treatment of Haemorrhoids

Diet: Haemorrhoids can be treated when individuals consume a fiber-rich diet in order to soften the stools and ease their bowel movements. Fiber-rich foods include fresh fruits, dry fruits, grains, vegetables, and cereals. About 20 to 30 grams per day of fibrous foods is recommended. Dietary fiber will help create bulk in the intestines which will help in softening of stools and ease bowel movement. Supplemental fiber available in the marketincludes psyllium husk, methylcellulose, and calcium polycarbophil. Other recommendations include increased intake of liquids and having stool softeners. Drinking enough water and liquids will prevent stool from hardening.
Over-the-counter topical treatment: There are various products available to treat hemorrhoids, such as gels, hydrocortisone creams, ointments, foams, pads, and suppositories.
Home remedies: Soaking anus in a warm sitz bath might also help in hemorrhoids for about 10 to 15 minutes per day. One should practice good hygiene and clean anus with warm water while showering. Avoid using soap and dry toilet paper. One can also use a cold compress on the anus.
Minimally Invasive Procedure for Hemorrhoids (MIPH)

Out of the various types of medical and surgical interventions available to treat Piles, Minimally Invasive Procedure for Hemorrhoids (MIPH) 0r painless stapler surgery is known to be very popular since it acts an alternative approach to surgical interventions made for piles.

MIPH is defined as a minimally invasive surgical technique in which a band of loose or prolapsed mucosa and sub mucosa in the rectum is excised, proximal to the piles and disrupted mucosa is fixed by  stapled end to end mucosal anastomosis.

This will ultimately occlude the blood supply to the superior hemorrhoidal artery above the hemorrhoidal tissue, resulting in the retraction of prolapsed mucosa back to its original anatomical position. A special circular stapler known as PPHO3 is used in the anastomosis and the whole maneuver will take around 30 45 minutes.
