Pain is an unpleasant sensory and emotional experience caused due to tissue damage or illness. It is caused due to injury and various diseases such as osteoarthritis, chronic arthritis, diabetic neuropathy, multiple sclerosis, stomach ulcer, fibromyalgia and cancer. It can be classified on the basis of duration as acute pain and chronic pain. Acute pain is sudden onset of pain where as chronic pain persists for long periods. Chronic pain is mainly caused due to aging conditions of bone and joints and nerve damage and injury. Pain is managed by a particular set of drugs or devices to treat pain. Transcutaneous electrical nerve stimulators, neuro-stimulators, analgesia infusion pumps and radiofrequency ablators are some of the pain management devices. Most of these devices block the pain gate mechanism, to block the passage of pain signals to the brain. Radiofrequency ablators destroys nerves by generating heat to block the pain signals, Similarly, neuro-stimulator devices uses mild frequencies of current to block the passage of pain signals. These devices help in treating various painful conditions such as cancer, musculoskeletal injury and neuropathic pain. Pain management devices help to reduce the risk of long term narcotics, non steroidal anti-inflammatory drugs, and other pain relieving medications.
