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.

Mobility for a person is very important, and when you look through, the hip is a very important component to this. It connects the upper and lower parts of the body and helps in movement. It is a ball and socket joint, where the hip bone provides a socket, into which the upper part of the thighbone (femur) sits into, allowing for free movement.

Like any other human organ, the hip also is prone to damage. Be it natural ageing, infection, injury, or diseases, hip movement can be affected, leading to limited movement and increased pain and stiffness. For these people, being able to get back a hip which will allow them to be back on their feet is a boon for sure. It helps in relieving pain and improving mobility, almost giving people a second lease of life.

Reasons for hip replacement:

With natural ageing, the hip joint can lose its ability to move, due to normal wear and tear of the hip and thigh bones
Diseases of the hips (infectious or autoimmune) can also lead to hip replacement
Injury or trauma is another major cause that requires hip replacement
Joint problems, leading to repeated dislocations
Tumours of the relevant bones
Understanding the procedure in detail

The affected bones (whether diseases or worn out) are replaced with a prosthesis which is compatible with the normal body tissue.
While some materials fuse to the natural bone, others do not and are simply placed as a separate unit
This is a surgery which requires hospitalisation and stays for up to 5 days depending on patient s overall health condition
The entire procedure may take a couple of hours and is usually done under general anaesthesia
An incision is made through the side of the hip
Both the hip and the thigh joints are prepared, diseased tissue removed, re-shaped, etc. to make way for the prosthesis
The prosthesis is introduced through the same incision and positioned into place
As noted earlier, there are two types. The ones which fuse to the bone have pores in them into which normal bone eventually grows.
The other variety is the cemented version, and a glue is used to keep it in place
Most doctors now use a combination, that is cement a porous prosthesis, into which bone will grow, and the incisions are closed
The patient stays in the hospital for 1 to 4 days depending on overall health
Once discharged, infection and pain control are continued
Exercise and physiotherapy play a major role in restoring normal function
Weight management is also very important

Hip Replacement - Understanding The Procedure In Detail!

Spine surgery is conventionally performed as  open surgery , which means the region being worked on is opened with a long entry point to permit the surgeon to view and access the area. Technical and scientific advances have permitted more back and neck conditions to be treated with a less obtrusive surgical technique. The minimal invasive spine surgery (MISS) does not include a long cut, and it prevents causing damage to the muscles around the spine. As a rule, this causes less pain after the surgery and a speedier and healthy recovery.

Spine surgery is normally suggested when non-surgical treatments like medicinal or exercise based methods have not helped in lessening the excruciating symptoms of your back problem. Moreover, surgery is just considered if your doctor can pinpoint the correct reason of your pain, for example, a herniated circle or spinal stenosis. 

MISS is also called less obtrusive spine surgery. In these procedures, surgeons utilise particular instruments to get to the spine through little cuts. The surgery process is as follows:

During the surgery, a little entry point is made and the tubular retractor is embedded through the skin.
It is also inserted into the delicate tissues down to the spinal cord.
This makes a passage to the little range where the problem exists in the spine.
The tubular retractor holds the muscles open and is set up all through the surgery.
The surgeon gets to the spine utilising the little instruments that fit through the focal point of the tubular retractor.
Any bone or disk material that is expelled goes out from the retractor.
Any gadgets needed for the fusion process, for example, screws or rods, are embedded through the retractor.
A few surgeries require more than one retractor.
Keeping in mind the end goal to see where to put the entry point and embed the retractor, the surgeon is guided by fluoroscopy.
This strategy shows ongoing X-ray pictures of the patient's spine on a screen throughout the surgery.
The surgeon additionally utilises a microscope to enlarge the view through the retractor.
Towards the end of the procedure, the tubular retractor is expelled and the muscles come back to their original position.
This restrains the muscle damage that is more ordinarily found in open surgeries.
It is very important to talk about these risks with your doctor before your surgery or procedure.

Infection: Antibiotics are consistently given to the patient some time before, during, and regularly after the surgery to reduce the danger of infections.
Bleeding: A specific measure of bleeding is normal; however, this is not commonly dangerous.
Pain in the grafted area: Some patients will encounter surgical pain at the bone joint site.
Recurring symptoms: A few patients may encounter a repeat of their side effects.
Pseudarthrosis: Patients who tend to smoke are more prone to pseudarthrosis. This is a condition wherein there is insufficient bone formation. In case that this happens, a minor surgery may be required.
Nerve damage: It is possible that the nerves or veins might be harmed during these operations. These complications are extremely uncommon.
Blood clots: Another complication is blood clots in the legs. This poses a threat because these clots can break off and settle in the lungs.

Tennis elbow is a condition which is characterized by a sharp pain on the outer portion of the elbow. This condition is also called  lateral epicondylitis  and it occurs when the muscles of the elbow are overused. The symptoms of pain tend to occur near the forearm when you bend your elbow or try to grip an object.

Causes
The elbow joint comprises of muscles which facilitate movement of the wrist, elbows and the fingers. There are tendons present in the elbow which join the muscles and bones, thus regulating the forearm muscles. When the muscles of the elbow are overused, then it can lead to inflammation and tears in the muscles.

This condition is so called as it is usually caused by playing certain sports, primarily tennis. It may also be caused by activities that put repetitive stress on the elbow. If the same pain occurs around the inner portion of the elbow, it is called a  golfer s elbow .

Prevention
The best treatment method to prevent tennis elbow is to strengthen your elbow muscles. You need to follow a regulated strength and stretching program directed at strengthening the muscles of the body, including the elbows.

Here are some tips to prevent tennis elbow:

Try to stay in good shape physically.
Use proper technique when you are carrying out any activity that involves the elbow.
Avoid overstressing the elbow joint with repetitive movements as it can cause injury to the tendon.
The muscles of the shoulder, arm and the upper back should be strengthened to prevent tennis elbow.
For movements that require you to twist your arm or grasp things, you can use a counter force brace to protect your elbow. This brace is worn on the forearm which redistributes pressure on the muscle. A counter force brace is recommended for people who are at an increased risk of tennis elbow.

Sciatica refers to the pain one experiences due to the irritation or compression of nerve roots contributing to formation of Sciatic nerve. The sciatic nerve is the longest and widest nerve in the body, running from the lower back, down to the back of each leg. The pain can occur in the lower back and spread to the hips, buttocks and leg. Sciatica generally affects one side of the body. There are numerous causes of irritation of the sciatic nerve and sciatica.
 
Some of them are:
 
1. Spinal Stenosis
The narrowing of the spinal canal caused by natural wear and tear of the vertebrae (individual bones in the spine protecting underlying nerves) of the spine is known as spinal stenosis. The narrowing may put pressure on the roots of the sciatic nerve, causing pain.
 
2. Herniated Disc
A disc is made up of cartilage and acts as a cushion between vertebrae, allowing flexibility of the spine. A herniated or slipped disc occurs when a disc is temporarily pushed out of place, putting pressure on the sciatic nerve.
 
3. Spondylolisthesis
It is a condition where one of the lower vertebrae slips forward over another. This also causes a collapse of the disc space between both, causing the nerve to get pinched. This may cause sciatica.
 
4. Piriformis Syndrome
Piriformis is a muscle found deep inside the buttocks, which connects the lower spine to the upper thighbone, running directly over the sciatic nerve. Spasming of this muscle can pressurize the sciatic nerve, triggering symptoms of sciatica.

5. Sacroilitis
Sacroillac joints are the place where the lower spine meets the pelvis and inflammation of one or both of these joints causes sacroilitis. This can give rise to symptoms of sciatica as it causes pain in the lower back, buttocks and legs.
 
6. Spinal tumors
Very rarely, tumors growing inside or along the spine may put pressure on the sciatic nerve.
 
7. Infection or injury
Muscle inflammation, infections, fractures or any other spinal injury may lead to irritation or compression of the sciatic nerve.
 
8. Pregnancy
Pregnant women may suffer from sciatica due to weight gain, expansion of the uterus or increased fluid retention or other changes occurring in the body, which put pressure on the sciatic nerve.
 
9. Other causes
Osteoarthritis and fractures caused by osteoporosis may also affect the sciatic nerve, producing symptoms of sciatica.

Top 9 Causes Of Sciatica Nerve Pain - You Need To Know About

Wounds and bruises are both injuries. However, they differ widely in terms of the causing factors, the nature of the injury, the pain they cause and the kind of treatment they require. The following are a few of the myriad ways in which the two injuries differ from each other:

1. A wound causes quick damage - the skin tissue is cut or punctured while a bruise (also called a closed wound) is where the skin is not torn. 

2. A wound is usually caused by a sharp object but bruises are the results of blunt force or trauma.

3. A wound almost certainly bleeds due to ruptured tissue and blood vessels. Blunt injury also damages the blood capillaries of the skin and causes blood to accumulate under the skin tissue, creating a dark patch of skin. Blood vessels can also break due to lifting of heavy objects or overexertion of muscles.

4. A wound carries the risk of infection because the skin is open but a bruise does not get infected.

5. A wound has a burning or stinging sensation but a bruise is characterized by swelling and a blunt throbbing pain.

6. A wound can be healed by antiseptic and antibiotic medication. Large wounds need to be closed by stitching them up to avoid severe infection. On the other hand, a bruise usually heals by itself. A cold compress and pain killers may be used to ease discomfort. Heat can be applied to the injured spot to normalize the blood flow and dissolve the blood clot.

7. A wound can lead to complications like bacterial infections or the healing might be delayed by chronic diseases like diabetes. In case of a bruise, it usually does not cause complications but if there's a blunt injury to sensitive areas like the head, the tailbone or the eyes, medical attention is advised.

8. Wounds and bruises can also be differentiated on the basis of their subtypes. The different types of wounds are:

a. Incision (sharp objects cutting the dermis layer of skin)
b. Abrasion (the epithelial tissue is scraped off)
c. Avulsion (a body structure is torn off)
d. Penetration (a sharp object causes an entry and an exit wound)
e. Puncture (only an entry wound caused by a sharp object)

The different types of bruises are:
a. Hematoma (blood pools under the skin)
b. Purpura (tiny spots of blood on the inside of the mouth)
c. Contusion (similar to hematoma and caused by external trauma)
d. Crush injury (caused due to a large amount of force on the body part for a long time)
