Pain Medicine is a discipline within the field of medicine that is concerned with the prevention of pain, and the evaluation, treatment, and rehabilitation of persons in pain. Some conditions may have pain and associated symptoms arising from a discrete cause, such as postoperative pain.
“Analgesics” is the term used for medications which are used for treating pain. They act by inhibiting the enzymes i.e. Cyclooxygenase (COX) which synthesize the prostaglandins.
