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.

Cervical spondylosis is a disorder that affects the joints and disc around the cervical region or neck. Earlier, it was believed that spondylosis can occur in old people only and is an age-related disorder. However, it is not true nowadays. Today, even youngsters complain of pain in the neck region due to cervical spondylosis. It occurs mostly to people who spend longer hours sitting and working on the computer. It is caused due to damage of cartilage and bones in this region. Symptoms of cervical spondylosis include chronic pain and stiffness around the neck.

Causes for cervical spondylosis-

A number of factors can be responsible for cervical spondylosis. Following are the common causes for the disorder:

1. Overgrowth of bones in the neck region: this can hamper the sensitive areas around the spine.

2. Drying of fluid: the spinal bone is made up of disc-like structures. There is fluid present in between the disks. Spondylosis is often caused due to the drying up of this fluid.

3. Herinated disks: in some cases, cracks get developed on the disks. This causes leakage of fluid in between them. Consequently, the nerves in this region get damaged.

4. Injury: if you have had an injury to your neck, such as during a fall or car accident, this can accelerate the aging process.

Homeopathic medicines to cure cervical spondylosis-

There are homeopathic medicines, which can cure cervical spondylosis over a period of time. However, the dosage of these medicines must be administered properly to get rid of the disorder. Some of these useful medicines have been listed below:

Now, for an exercise which is so simple, is it not worth it?
Side Stretch: Talking about stretches, another form of a stretch happens to be the side stretch. Even this is rather simple and all that needs to be done is to lie on one s side and pull the ankle of the leg which is not in contact with the ground towards the back. While this is being done, the ankle of the lower leg should apply pressure on the thigh.
Straight leg raise: It may seem that most of the exercises which reduce pain are stretches! However, this is not really the case as there is a place for exercises such as the straight leg raise and the like. What exactly is the straight leg raise? Well, it can be done when a person is either in a sitting position or is lying on his or her back. The toes are to be kept pointed upwards and the leg is to be raised. It is to be kept in mind that the challenge of the straight leg raise is that the knee should not be bent, at all.
The cat and camel exercise: The terms cat and camel generally refer to members of the animal kingdom. However, jointly, in terms of exercises, the cat and camel is an exercise well worth remembering as it can save the individual quite a lot of pain. All that needs to be done is to alternatively arch one s back towards the floor and the ceiling while resting on one s hands and knees.

The neck and shoulder have a huge range of movement and thus they are more prone to injury. The ball and socket joint at the upper arm is the shoulder and both the neck and the shoulder are made up of soft tissues, muscles and ligaments. 

Reasons behind pain Injured rotator cuffs: 

Rotator cuffs are the tendons supporting the shoulder. If they are injured it might lead to a chronic loss of the range of movement. This is more commonly known as a frozen shoulder. 

Dislocation: Dislocated disc of the neck or shoulder due to an accident would cause severe pain in the affected area. 
Fractures: Fractured collarbone or the upper arm bone may result in chronic pain. 
Tendonitis: This occurs due to the over usage of the arms or neck or strains due to over exertion like in sports. 
An unstable shoulder joint: If there is instability in the ball and socket joint of the upper arm, chances of having a chronic pain is high. Others: Degenerative arthritis, herniated disc, and even heart attacks can be the other possible causes of chronic neck and shoulder pain.

Diagnosis for shoulder and neck pain X-ray: 

The main form of diagnosing a pain is an x-ray. It helps to reveal diseases from arthritis, tumour, slipped disc, narrowing spinal cord, fractures and spinal cord instability. 

MRI: Magnetic Resonance Imaging or simply the MRI reveals the detail of nerve-related issues along with the problems in the ligaments and tendons. 
CT scan: There may be instances when the injuries are difficult to be diagnosed. And, in the case of a fracture, a CT Scan is advised for more details. It is also an alternative to MRI. 
ECG: An Electrocardiogram is a way of diagnosis if shoulder and neck pain continues along with chest pain or shortness of breath. If there is a risk of an individual having a heart attack, then an ECG is recommended. 
Electro Diagnosis: Electromyography referred to as EMG and Nerve Conduction Velocity (NCV) are used to diagnose pain in the arm, neck, shoulder followed by a numb feeling on the affected areas. 
Treatment for chronic shoulder and neck pain 
A simple sprain on the neck and shoulder would demand a rest for a few days along with pain medication. If the pain is due to muscle spasms application of dry or moist heat may provide relief. In the case of a swelling due to injuries, a cold ice pack 4 to 8 times a day will provide immense relief. Patients might be advised a cast or sling for the shoulder pain. The soft tissues in the neck and shoulder can be treated with pain relievers taken for a few days. Muscle relaxants are also prescribed depending on the severity of the pain. Local corticosteroid injections are helpful for shoulder arthritis. Platelet rich plasma injection is another modern treatment for arthritis or tendinopathy. In some situation, radio frequency procedures are very helpful. Exercises are very effective for both neck and shoulder pain movement. Surgery might be an option if nerve roots are affected.
