I have just been told I probably have fibromyalgia. My question is what does the muscle pain feel like? My body twitches, I have tender points on both knees with stabbing pains in my legs all over as well as my hands. Although this all is concerning to me, what scares me more is the pain I get in my knees. It almost feels like there is something eating away at the joints in my knees. Does this sound like fibromyalgia? I have had ex rays and there is no arthritis in my joints. I'm still very active but always in pain!
