I was diagnosed about 4 years ago with fibromyalgia. The pain has always been mild for the most part, occasionally moderate. My pain is a deep ache all over my body. Feels like my bones hurt. The last couple months the pain has been getting worse. I've also started having pretty severe pain in the joints of my fingers, wrists, knees, and ankles. Testing for arthritis is negative and no swelling. I take Cymbalta, which used to keep the pain manageable. However it is getting so bad that I can barely stand it. Any treatment suggestions?
