Almost each one of us might have suffered from pain at one or the other point of time in life and you cannot always ignore it by considering it to be routine. As sometimes, pain can be an indication of underlying diseased condition such as arthritis; which has to be rectified early at its onset. Scientifically, pain can be defined as a defence procedure, structured by human body to inform brain about the damage or injury that has taken place.
Apart from physical sensation, pain can as well increase emotional turbulence, leading to nervousness or depression. Thus chronic pain has direct link up with unusual neuronal damage; which if left untreated, may lead to fatal conditions.
Pain can be due to any condition, such as damage to cartilage as in case of osteoarthritis or chemically activated neuronal inflammation as in case of rheumatoid arthritis. Whatever may be the reason, it has so far proved to be challenging to both doctor as well as patient; to identify the cause and manage symptoms of the pain.
