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.

Treatment of frozen shoulder varies depending on the stage it is at, and how severe is the pain and stiffness. There is no outright cure and the aim of treatment is to keep the joint as mobile as possible. The most effective treatment is that which maintains a good range of movement until the shoulder starts to heal. 

Treatment may Include the following:

1. Shoulder exercises: Regular, gentle exercise can help to keep the shoulder joint mobile. If your shoulder is very stiff, exercise may hurt, and it should only be carried out with the guidance of your doctor or physiotherapist. If you are able to, continue using your shoulder as normal saving' the shoulder can cause the muscle to waste and may make stiffness worse.
2. Painkillers: Over-the-counter painkillers such as paracetamol or prescription-only drugs such as codeine may be taken to ease pain and you should discuss this with your general physician or pharmacist.
3. Anti-inflammatory painkillers: Such as ibuprofen and diclofenac, are often prescribed to ease pain and inflammation. Any medication that you take should be discussed with your general physician or pharmacist.
4. Steroid injections into or near the shoulder joint may be effective at relieving pain and inflammation for a few weeks. However, injections are not a cure, and symptoms may return.

In preparation for the possibility of conception, a woman's body undergoes the menstrual cycle every month which culminates into the periods. This is a normal process which all women of reproductive age go through every month. However, in certain cases, the periods can be really painful where you may suffer from menstrual cramps or could be generally in much pain. This condition is known as Dysmenorrhea.

What exactly is Dysmenorrhea
As mentioned above, Dysmenorrhea is a disorder that many women got through while having their periods where they may suffer from painful cramps. The pain usually occurs in the pelvis area along with the lower abdomen and it may also be accompanied by other symptoms.

Some symptoms of Dysmenorrhea
Some of the symptoms of Dysmenorrhea could be any combination of the following factors
I. Very painful menstrual cramps accompanied by lower back pain
II. Diarrhea and nausea along with the cramps
III. Pain in the inner thighs, lower back and hips
IV. Being hypersensitive to light, loud sounds, specific smells and touch
V. Being fatigued all the time, even causing you to faint

Causes of Dysmenorrhea
Dysmenorrhea is usually caused by the contraction of the Uterus. While the uterus does contract a little even in normal periods, during Dysmenorrhea the contractions tend to be a little too much. Due to this the uterus presses against the blood vessels and organs within the vicinity causing oxygen loss to them. This causes elevated levels of pain and discomfort.

Some of the underlying causes which may result in Dysmenorrhea are:
1. Narrowing of the cervix - Also known as stenosis, the lower part of the uterus which is the cervix may become narrow due to scarring and cause Dysmenorrhea.
2. Endometriosis - This is where the uterine lining is found outside the uterus, especially in the pelvic cavity and thus may cause painful cramps.
3. Inflammatory pelvic diseases - This is when a bacterial infection in the pelvic area can spread to multiple organs, including the uterus and thus may cause painful menstrual cramps.
4. Tumors - Tumors or fibroids which are unwanted growths on the inside of the uterus may also trigger Dysmenorrhea.

What to do if you are suffering from Dysmenorrhea
Below are some of the basic steps which you can take to ease pain from Dysmenorrhea
1. Avoid smoking and abstain from alcohol
2. Ample rest during periods
3. Keep the body dehydrated
4. Don't consume foods high in salt
5. Don't drink coffee or any caffeine rich foods
6. Lower back massages and hot water bag treatments to relieve pain
If severe pain still persists for long or if dysmenorrhea occurs repeatedly, then you should consult a doctor first rather than trying to resolve the problem yourself.


All about Dysmenorrhea

Pain management is an issue that stares back at mankind, irrespective of the underlying health condition. Whether it is a headache or a back pain, burn or fracture, heart attack or cancer, pain is always a symptom. In some cases like migraines, cancer, etc., the pain is chronic and the patient needs to be constantly on the vigil to know when an attack will ensue. This has also put high pressure on the medical fraternity to identify ways that can provide relief to these people. Various methods have been identified, and one of them is the electrotherapy.

What is done?
A few electrical impulses are directed at the area of the pain using a hand-held device. This is similar to providing electric shocks of mild intensity to the affected area (forehead, low back, neck, etc.). What this does is stimulate the nerve endings, improves circulation and muscle strength and promotes bone growth and tissue repair. The end result of all this is overall improved functioning and pain relief. Depending on the actual condition, the sessions will have to be repeated. In some patients, the electrotherapy is used in conjunction with other therapy so that they can go about their routine exercise and pain relief.
The sessions may also have to be repeated as most often these are used in individuals with chronic pain. They are also helpful in providing relief during the acute attacks.

How does it work?
The most common form of electrotherapy is known as TENS, which stands for transcutaneous electrical nerve stimulation. The area to be treated is cleansed with spirit and then small sticky pads are applied through which the electricity is passed. A hand-held device is used, through which electrical impulses are passed to the skin, which stimulates the nerve cells to provide relief from pain. It causes a vibrating and tingling sensation in the treated area. It is believed that it blocks the nerve impulses and therefore provides pain relief. Another theory states that they promote the release of endorphins which are natural painkillers; it is also very effective in case of migraine and sciatica and neck pain where the chronic pain is coupled with acute spurts.

With narcotic painkillers having various side effects, techniques like electrotherapy are gaining popularity. A small catch also is that it does not work for everybody and in most people with back pain, fibromyalgia, and migraines, requires repeat sessions for relief. The cost of each session also needs to be considered against the extent of relief achieved. However, for those whom it works, it is a very good technique for chronic pain control.

Electrotherapy - How It Can Help In Managing 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!

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.
