Possible Causes
The exact causes of fibromyalgia still are not known. However, recent research suggests that changes in the central nervous system may be responsible for the chronic pain that comes with fibromyalgia.
Every part of the body receives electrical signals from the nerves in your brain. But sometimes, these nerves can get damaged. And damaged nerves sometimes send extra signals. Signals that healthy nerves would not send. These extra signals may cause pain.
Nerve damage may occur for a few reasons. For example, a viral or bacterial infection. Nerve damage could also be linked to injury.
