The World of Chronic Pain


Why Does It Hurt?

Chronic pain continues after the injury or disease should have healed but for some reason the nerves in the area continue to transmit pain signals to the brain. Cases exist where brain chemistry misfires and causes pain when there is nothing wrong with the body.


Chronic Pain

Chronic pain is defined as pain associated with a condition that lasts more than three months. People with chronic pain define it as living in an ongoing state of hideous torture.


Acute Versus Chronic Pain

It is useful to distinguish between two basic types of pain, acute and chronic, and they differ greatly.
