Extreme muscle pain in legs, upper arms, shoulders, and lower bacK. I thought I was just working too hard in my garden but nuscles never ached while I was at work, only after I sat or lay down afterwards. Lately it has become very difficult to get up once I'm lying down. My neck and shoulders stab when I move them, and my lower back has a kinfe-like pain when I try to get up from a lying position. My neurologist has just ordered a blood test to check for the possibility of what he called an extremely dangerous side. For several years, I've had trouble with imbalance and tingling in hands and feet. I am looking forward to hearing the test results. Problem is, he says, just getting off he drug might not cause the symptoms to disappear. I feel frightened. I've been taking lipitor andfive years or more.
