First I was on Lipitor, then a new doctor prescribed Crestor instead and then prescribed Niaspan along with the Crestor. Now I have elevated muscle enzymes and even though I stopped the medication more than a year ago the enzymes continue to rise. I'm worried and I feel pain at intervals. Sometimes I don't even feel like getting out of bed and I have permanent damage to my abductor magnus muscle and it's extremely painful to walk upstairs. Now I have to walk upstairs like a child and have to use the handrail to pull myself up while putting more weight on my right leg. I used to walk 2 miles a day for exercise. I can no longer do that. I also have short term memory loss, insomnia sometimes and muscle loss in my forearms to the point where my arms look like I'm 85 years old and I'm only 61. Has anyone else experienced anything like this?
