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.

Back pain is a common source of pain and can be acute, sub-acute or chronic in nature. Back pain is classified along the segments of the spine and can be divided into neck pain, middle back pain, lower back pain and coccydynia or tail bone pain. Back pain can be quite troublesome as it disables a person to move about freely due to constant ache.

Here are some procedures for the treatment of back pain.

    Give your back some rest: Most people who get back pain become obsessed with it and end up getting MRI scans and x-rays done. Some even take injections and other such measures without recognizing the intensity of the pain. It is advised not to rush into the matter immediately and the simplest way to cure the pain is by resting. 90% of pains in the back resolve by themselves in 6 weeks and so you must give your back a break instead of taking medical actions and let time do the healing.
    Pills: While you let time treat your back pain, sometimes the pain increases and gives you a bad time. In this case, you can take anti-inflammatory medicinal pills such as ibuprofen or naproxen. These pills will help you ease the pain. However, using such pills for a continued period of time causes side effects such as gastrointestinal disorders. Hence, you should not take them for more than ten days at a stretch.
    Hot and cold compress: Apply a bag of frozen peas or an ice pack to the affected area for 48 hours after the pain appears. Every session should be about 20 minutes, and you should take more than two sessions each day. After two days, repeat the same procedure using a heat pad instead of ice. The cooling procedure shuts down your blood capillaries and reduces the flow of blood to that area. The swelling is eased as a result. The heating, on the other hand, loosens tight muscles and increases the blood circulation, providing extra oxygen.
    Change your mattress: People who sleep on firm mattresses and cushions on their beds are at a higher risk of having a back pain. According to studies, it has been observed that people sleeping on medium-firm mattresses have healthier backs. In case your mattress in sagging or is over 8 years old, you should replace it.
    Acupuncture: When your back pain is very severe, you can resort to acupuncture, which provides efficient pain relief. The procedure changes the way your nerves react and reduces inflammation.

Back pain arises from various reasons and should always be taken care of. Unattended back pain worsens and makes the affected person suffer.

Suffering From Lower Back Pain - 5 Ways You Can Treat it

Knee replacement can be extremely painful. Previously, opioids or narcotics were administered for pain relief. But excessive addition of opioids is not exactly effective for controlling pain. 

Multimodal pain management has become an important part of the perioperative care of patients undergoing total joint replacement. The principle of multimodal therapy is to use interventions that target several different steps of the pain pathway, allowing more effective pain control with fewer side effects. Many different protocols have shown clinical benefit. The goal of this review is to provide a concise overview of the principles and results of multimodal pain management regimens as a practical guide for the management of joint arthroplasty patients.

Multimodal denotes administering two or more than two types of medications that work with different mechanisms. The following are the techniques used:

Pre-operative Femoral Nerve Block: Prior to the surgery, a catheter is placed beside the femoral nerve for blocking it. This nerve is located in the upper thigh. Medication is delivered through the catheter for the nerve to be numbed for 24 hours. Thus, pain signals to the brain are blocked. This method reduces the use of narcotics and the consequent side effects.

Patient Controlled Analgesia (PCA): This method is also known as  Pain Pump . An intravenous pump is used to administer pain relief medications, such as oxymorphone or morphine, after the surgery. The control button of the machine could be pressed, by the patient for 6 to 10 times per hour. The machine is used for two post-operative days.

Oral Medications: The oral medications include Non-Steroidal Anti-Inflammatory drugs or NSAID; such as Celebrex which is similar to aspirin, structurally. Alternatively, acetaminophen, such as Tylenol or its equivalent composition, can also be used.

Acetaminophen: It acts on the Central Prostaglandin Synthesis and relieves the patient of pain through multiple mechanisms.

Epidural Analgesia: It produces lower pain scores and involves less time for achieving physical therapy goals. However, this is subject to side effects such as dizziness, urinary retention and itchiness.

Gabapentinoids: These medications include membrane stabilizers such as Gabapentin and Pregabalin.

The objective of multimodal treatments is to provide quick relief to the patient and immediately so. Earlier the rehabilitation, more successful will be the knee replacement surgery.

Neck pain is a very common problem found in people who are habituated with a wrong posture for extended periods in a day, day after day. While old age and arthritis contribute to neck pain, even younger individuals who sit for hours in front of a computer screen or just generally have a faulty posture, may be subjected to such pains. Neck pain is usually due to cervical spondylitis.

While most of the neck pains are cured by topical muscle relaxants, those who have a severe condition may not be able to touch their chest with their chin, may have a loss of strength in one arm, may have shooting pain in one arm or shoulder, or may experience a sudden change in the bowel habits. In these situations, it is best to consult a doctor at the earliest.

The homeopathic remedies for neck pain are as follows:

Cimicfuga: This remedy is usually recommended when the neck pain radiates out and is almost like an electric shock spreading to the left arm. Pain and stiffness is experienced by the individual undergoing such a condition, if the hand is pulled backwards. Damp and cold conditions are aggravating factors, whereas warmth, pressure, and rest provide relief.
Chelidonium: This remedy is usually recommended when the neck pain is associated with heaviness and tenderness. In such a condition, the pain may also affect the right arm, shoulder or wrist. Touching or moving the arm is an aggravating factor and relief is provided with warmth.
Gelsemium: This is the medication of choice when soreness and tenderness in the neck region along with a persistent headache is the condition. Pain intensity keeps changing and the patient feels very weak and lethargic. To relieve the pain, the patients are advised to lie down with their head raised. Aggravation of the pain happens due to cold and damp conditions.
Causticum: When the muscle and tendons undergo stiff contractions and the muscles of the neck are weakened, Causticum is the remedy of choice. Patients are unable to move their head to the right and find it extremely difficult to be able to bend it backwards. Pain in the neck is excruciating and accompanied with a tearing and burning sensation. Movements aggravate the pain and heat exposure provides relief.
Bryonia: A stitching sensation in the neck, which seems to extend upto the shoulders, is when Bryonia is prescribed. Swelling accompanied with a feeling of heat in the shoulders is also present. Movements increase the pain while relaxation of the shoulder and neck region brings relief.
The aforementioned options are the treatment lines of choice in case of a neck pain. They are universally accepted to be safe options, sans side effects, and that s why most patients prefer them.
