Recommend Treatment For Joints Pain

My husband just went back to bed at 10 a.m. He said he felt that he was out of it, as if he were having an acid flashback, and he felt nauseated. The last few months he's been stiff and aching in his joints. His doctor took him of statins to see if the muscle stiffiness was a side effect, but he has'nt felt better in the nine days he's been off them. Now this new development. I'm very worried. --Lorna
