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.

Treating Knee Pain With Homeopathy Treatment

Knee is a hinge joint where the lower leg bone tibia meets the thigh bone femur. During osteoarthritis, cartilage or ligament defects and degenerative arthritis, knee replacement surgery is recommended world-wide to get relief from extreme pain. Knee replacement surgery, also known as knee arthroscopy, is a surgical procedure, in which the affected knee joint is replaced with synthetic material. The most likely candidates for total knee replacement are the patients with severe destruction of the knee joint coupled with progressive pain and impaired function.

Modern technological advances have made computer assisted knee replacement surgery extremely popular around the globe. In this surgery, the surgeon is assisted by a computer to remove the optimum amount and angle of the bone, which otherwise is done by inspecting manually. This is an excellent example of surgery through small incision and it eliminates the chances of human error. A perfect alignment and balance is achieved and hence longevity is also increased to 20 - 30 years. Knee replacement surgery is also specific to gender as the anatomy of male and female patients is different.

There are many types of knee replacements, most common being the total knee replacement or Total Knee Arthroplasty. In addition, there is partial knee replacement, bilateral knee replacement, revision knee replacement and knee arthroscopy.

In knee replacement surgery, the worn out surfaces of joints of knee are replaced with artificial implant of plastic and metal. The lower end of the femur bone is removed and replaced with a metal shell. The upper end of the lower leg bone (tibia) is also removed and replaced with a channelled plastic implant with a metal stem. A plastic ball is also added under the kneecap depending on its condition. These artificial components are commonly referred as prosthesis. The design of these highly flexible implants replicate knee, with the rotating knee replacement implants assist in backward and forward swing of the legs.

Patients whose knee joints have been damaged by either trauma or progressive arthritis should consider total knee replacement surgery. Post-surgical hospital stay after knee joint replacement is usually three to five days. The surgery has a very high success rate and shows dramatic improvement after a month. This improvement is most notable one month or more after surgery. The pain caused by the damaged joint is reduced significantly when the new gliding surface is constructed during surgery. Initially, patient will walk with the help of a walking aid until the knee is able to support full body weight. After six weeks, patient can walk comfortably with minimal assistance. Patients with artificial joints are prescribed to take antibiotics during the course of any elective invasive procedures including dental work. Physiotherapy is an essential part of rehabilitation and it will increase the muscle strength and patient can enjoy most activities, except running and jumping.

Three Ways to Protect Your Knees

The knee is known as the largest and one of the most complex joints in the human body, and also one of the most vulnerable, as it supports the weight of the entire body. The knee joint is made up of several elements including the knee cap, meniscus, connective tissue, tendons, ligaments, cartilage, and muscles. Damage to any part of the knee can cause chronic pain. So how can you protect your knee from damage and injury? Take a look at these three points!

Dealing with Load: Weight is a big one. Carrying around extra pounds and kilograms can be detrimental for your knees in the long run. Your knee is not equipped to handle the excessive weight. It already supports three to five times your weight when you get up and walk around or indulge in some mild jogging. One must be careful of those extra pounds to take the load off the knee and keep it from falling prey to damage.

Exercise: Moderate to intense exercise is prescribed for one and all. This, of course, depends on one's overall health and age. If you are already suffering from joint pain, then you may want to go easy on the exercise with a focus on building muscle strength and foundation. If you are healthy, then some amount of daily exercise as a routine will keep those knees in prime working condition and well lubricated as well. Inactivity and a sedentary lifestyle can affect the knees very badly.

Do not Ignore: Warning signals such as chronic or acute knee pain should not be ignored. Remember to see a doctor or an orthopaedic specialist to find out if you have contracted an infection or if you may have suffered a fracture due to an injury. Also, it is important to take a bone density test regularly, especially after the age of 40 or for women going through menopause, as this will point to any deficiencies and even warn you in case there is any trace of osteoporosis.

Rest, exercise, and food should be kept in fine balance for a healthy body. These are a few measures that one can take to keep knee pain at bay. Yet, it is also advisable to speak with a doctor at length regarding measures to protect your knees.
