How Can Pain All Over The Body Be Treated?

Every evening about 6 PM, my entire body has such deep spreading pain. As soon as I sit down to relax, the pain radiates through my wrists, arms, elbows, shoulders, legs, and back. I nearly groan out loud with the pain and become terribly exhausted. Lying down makes it worse. Sometimes, between spasms, I fall asleep for a minute of less while watching TV in a recliner, and that helps relax my body for about 15 minutes. I am on 1 mg ropinirole HCL at dinner time which helps. When I go without, the pain keeps me awake until 3 AM or later. Pain meds do not help. Walking around does not help. One of my doctors said the pain is from a variation of restless leg syndrome. Since it responds to ropinirole, that makes sense. Your opinion will be appreciated. Thank you.
