Scientists develop a cure for chronic pain in joints, back and muscles

The pain signal comes from a lesion in the spinal cord, then to the brain. In the Central nervous system there is no center of pain, and for chronic pain respond the same sites as for acute pain.

In chronic pain the nerve endings continue to send the brain signals, even if no damage in the joints or muscles no. It's hard to explain. Perhaps the neurons in group A11 are responsible for chronic pain. Try to disable them is one of the tasks of scientists.
