Pain

What Is Pain?

Because perception and tolerance of pain vary widely from individual to individual, pain is difficult to define and describe. Essentially, pain is the way your brain interprets information about a particular sensation that your body is experiencing. Information (or "signals") about this painful sensation are sent via nerve pathways to your brain. The way in which your brain interprets these signals as "pain" can be affected by many outside factors, some of which can be controlled by special techniques.
