Pain is a general term that describes uncomfortable sensations in the body. It stems from activation of the nervous system.
Pain can range from annoying to debilitating. It may feel like a sharp stab or dull ache. It may also be described as throbbing, pinching, stinging, burning, or sore.
Pain may be consistent, it may start and stop frequently, or it may occur only under some conditions. It may be acute, developing suddenly and lasting for a short period of time. Or it may be chronic, with ongoing sensations that last or return repeatedly over several months or years.
Pain may be localized, affecting a specific part of your body. Or it may be generalized, such as the overall body aches associated with the flu.
People respond to pain differently. Some people have a high tolerance for pain, while others have a low tolerance. Pain is highly subjective.
Pain lets us know when something is wrong and gives us hints about the cause. Some pain is easy to diagnose and can be managed at home. Other types of pain are signs of serious health conditions that require medical attention to treat.
