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

The Anterior cruciate ligament (ACL) is an important ligament that gives stability to the knees. An injury to this ligament can result in a host of complications and discomfort. Children or adults who are into sports such as gymnastics, volleyball, tennis, basketball, soccer, football, often injure this ligament. As per various studies and surveys, ACL injury is more likely to affect female athletes as compared to their male counterparts.

Depending on the severity and extent of the damage, an Anterior Cruciate Ligament Injury may be ranked on a grade of 3.

Grade 1 sprains indicate a mild injury or stretching of the ligament, seldom affecting the stability of the knees.
Grade 2 sprains are indicative of a partial ligament tear (the ligament loosen up). The damage is still under control.
Grade 3 sprains are extensive and severe, indicating a complete ligament tear (the ligament often breaks in two pieces). With a complete ligament tear, the stability of the knee is also affected (the knee becomes highly unstable).
What causes Anterior Cruciate Ligament (ACL) Injury?
While a host of sports activities mentioned above increases the risk of the injury, a person may also suffer a partial or a complete anterior cruciate ligament tear under the following situations.

A jump down a ladder, a tree, or a wall. An incorrect jump or a landing may be equally responsible for the ligament tear.
A collision or a hit, especially on the knee (while playing football).
Slowing down suddenly while still in running motion. A person suddenly stopping or missing a step can also injure the ligament.
Symptoms associated with ACL injury

An excruciating pain (especially in the back and outside of the knee) is often seen in people with a complete ligament tear (the movement is yet not affected). However, within a few hours, there may a swelling around the knee, indicating the severity of the injury with internal bleeding within the knee joints.
There may be restricted knee movement. The knee also feels unstable, further limiting the movement.
Sometimes a pop in the knee can be heard just at the time of the ACL injury.
Prolonged ACL injury left unattended can result in a painful complication such as knee osteoarthritis.
Diagnosis
To diagnose the extent of the damage, the doctor may suggest

Physical examination, including a quick brief about the case history.
Imaging tests such as X-rays and MRI can go a long way to analyze the ligament injury.
In the case of extensive swelling of the knees, the doctor may carry out an arthroscopy to have a closer look inside of the knee.
An accurate and timely diagnosis is important to avoid the aggravation of the injury. In the case of swelling and knee pain, consult a doctor, and get yourself thoroughly examined.

Anterior Cruciate Ligament Injury- Causes, Symptoms, and Diagnosis

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.



Why You Can Get a Slipped Disc Problem?

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!

The toes and heels are the most load bearing components within your feet which take most of the weight when walking, running, exercising or even standing up. The heels are an especially vulnerable part of the body which can become painful either due to injuries or excessive stress put on it.

4. Arthritis: The deposition of uric acid crystals in parts of your body may result in arthritis; this is a fairly common cause for heel pain as well.

Treatments available

1. Change in shoes: Shoes play a major role in the development of heel pain. You will either need to change the shoes or adjust the heels to ensure that they are at an equal and comfortable height and keep your posture natural and balanced.

2. Foot supports: There are specialized heel supports and wedges, which you can wear with the footwear. These supports help redistribute weight from the problem areas and uniformly distribute it among the other parts of the foot. Heel cups are also another form of supports you could try.

3. Pain relief medications: Sometimes aspirin or ibuprofen may be required to numb and dull the pain, if getting through the day becomes difficult or you are in the middle of work.

4. Resting: Sometimes resting is the only medication you can take to relieve the pain as it can only subside once the underlying conditions are corrected.

5. Ice packs: Cold compress and cold therapy would definitely help in numbing the area and providing temporary pain relief.

It is however, advisable to visit the doctor if the pain persists and take specialized medical care in more complicated cases wherein the pain is prolonged.
