Patients experience pain that's amplified in muscle sites over the entire body.
It's usually accompanied by a co-existing sleep disturbance where patients are up and down and don't get a good restful sleep throughout the night. It may be associated with overwhelming fatigue.

We're recognizing that it affects an increasing number of older individuals.
