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.

Vertebroplasty means shaping the backbone i.e. vertebra for backbone and plasty is related to shape. This is an outpatient procedure done to treat compression fractures of the spinal cord. The backbone is made up of multiple small bones which are stacked one on top of the other with a filling material in between that is known as vertebrae. The stack of bones are held in place by the soft, elastic vertebral material. 

Vertebroplasty & similar procedure called kyphoplasty is a non-surgical procedure where collapsed vertebrae is brought back to shape by injecting medical bone cement under fluroscopy / image intensifier in OT, thereby relieving pressure on the spinal cord or spinal nerves with special canula directed to the core of vertebral body. Indicated in osteoporotic vertebrae, spinal fracture, metastatic tumour or primary tumour of spine. This technique has replaced major surgery done earlier to reshape & fix vertabrae.

Technique: Bone cement, in a semisolid state, is injected into the weakened or fractured bone space. Once this solidifies, it provides additional support to the spine, enabling normal movement. It also helps in reducing the pain significantly and improves the overall mobility.

Procedure:

In what takes about an hour, the following steps are done. Earlier, a few decades ago, this would be an open surgical procedure. However, with advance technology, now it is done using a small incision

Local anesthesia is given in the area that needs to be operated
A biopsy needle is inserted into the fractured space with the help of an X-ray
The acrylic bone cement is injected into the bone space with a needle to fill up the space, once it solidifies, it stabilizes the vertebral space
The needle is removed and the incision is covered with a bandage
Usually the patient is sent home in an hour s time unless the overall condition is really bad
There could be some soreness at the site where injection is given, but one can notice a significant reduction in pain from the day of the procedure
There is also improvement in mobility while doing daily chores
The pain relief can last up to 3 years after the procedure
Returning back to normal activities takes about 3 to 4 days after the procedure
When to use this procedure?

Vertebroplasty is usually done in case of non-radicular pain that is intractable. In most cases, they do not respond to traditional therapies including physiotherapy, pain medications and even surgery. The pain could be due to:

Osteoporosis
Cancer metastasis
Myeloma
Spinal hemangiomas
Traumatic fractures
Benefits of using vertebroplasty for managing pain 

Minimally invasive
Effective way to get relief
Improves mobility
Cost-effective
Reduces need for long-term use of painkillers
Stabilizes the spine and prevents further collapse

Vertebroplasty - How It Can Help Manage 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. 

Hot & Cold Therapy - How It Can Treat Pain?

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.

Pain in the Hands or Legs!

Conventional medicine treats pain with the help of medications; by either blocking the transmission of pain signals in the body or by correcting the underlying problems caused by the pain in the first place. However, traditional and alternative forms of medicine such as acupuncture manage pain issues within the body through the means of redirecting disrupted energy flows. One of the very few forms of alternative treatments used in conjunction with conventional treatments, acupuncture is seen as a mercurial rise in popularity in the past few decades.


What is acupuncture?
Acupuncture dates back to ancient China, about 2500 years ago. It has been widely practiced there for a number of millennia, not only pain relief, but also for treating many ailments. Acupuncture isn t just considered a form of therapy, but a holistic form of medicine. Acupuncture works on the principle of the flow of energy within the body, also known as  Qi , in traditional Chinese medicine. Acupuncture strives to correct the disruptions in  Qi  that may cause pain by manipulating over 2000 of the specific pressure points within the body with the help of specially created needles.


Where is acupuncture effective?
Acupuncture is very effective in treating a host of ailments, especially in relieving the associated pain. Some of the areas where acupuncture has proven its effectiveness are:
1. Treating nausea and vomiting caused due to chemotherapy treatment for cancer patients
2.  Very useful in treating post-operative pain caused due to dental procedures
3.  Rehabilitating patients who have suffered strokes
4.  Fibromyalgia (musculo-skeletal pain with fatigue accompanied by sleep and memory issues) 
5.  Effective in combating withdrawal symptoms caused due to addiction
6.  Pain from menstrual cramps
7.  Tennis elbow
8.  Osteoarthritis (a type of arthritis caused due to the erosion of tissues present at the ends of one s bones)
9.  Pain of the lower vertebrae within the spinal column
10. Asthma


How does acupuncture work within the body?
According to modern medicine, the specific pressure points utilized by acupuncture within the body help in releasing chemicals that can block or at least reduce pain. It encourages the flow of chemicals from the brain, which act as nerve and pain blockers. It also helps stimulate the muscles and nerve endings, which can lessen inflammation and thus help in reducing pain.

Acupuncture - Why Should You Use it to Combat Pain?

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.
