Pain: Overview

Pain is a very common symptom that can affect almost any region of the body. Common types of pain include headache, knee pain, foot pain, wrist pain, leg pain, toothache, eye pain, ear pain, and many other types. Pain can be acute (e.g. from injury) or there are various chronic pain syndromes. Pain may result from various body tissues: muscle pain, bone pain, joint pain, nerve pain, and other types. Pain may be caused by physical injury, infection, inflammation, nerve damage (neuropathy), chemical imbalances, endocrine disorders, or various other causes. Pain needs to be distinguished from paresthesias (tingling/numbness), muscle spasms, and other similar symptoms.

Pain in its most benign form warns us that something isn't quite right, that we should take medicine or see a doctor. At its worst, however, pain robs us of our productivity, our well-being, and, for many of us suffering from extended illness, our very lives. Pain is a complex perception that differs enormously among individual patients, even those who appear to have identical injuries or illnesses.
