What qualifies as chronic pain?

[tanyajack]

The feeling of pain comes from a series of messages that zip through your nervous system. When you hurt yourself, the injury turns on pain sensors in that area. They send a message in the form of an electrical signal, which travels from nerve to nerve until it reaches your brain. Your brain processes the signal and sends out the message that you hurt.
