severe muscle pain and joint pain aching all over. My right thumb has started hurting and popping. Until reading everyones symptoms, I thought if was "old age" arthritis. I've been taking 20mg Pravachol until 1 yr. ago when it was increased to 40 mg. I think I will be throwing them out tomorrow and trying a diet. Depression is so much a part of chronic pain and I have never been depressed until now. Anyone else out there having same reactions?????
