What is pain?

Pain is a signal from the central nervous system indicating that something is wrong. Pain can actually be helpful; it alerts the brain to take action. Pain is a subjective experience; it differs for each person.

Acute pain

Acute pain is short-term pain that develops suddenly. It is caused by tissue damage, inflammation, or other disease processes. It tends to be sharp or intense before slowly calming. Acute pain can last for a few seconds or occur for up to six months. The purpose of acute pain is to protect the body from serious injury or further injury.

Examples of acute pain include, but are not limited to, the following:

  • Surgery
