Crazy day symptoms and conditions

I started taking Lipitor a month or so ago and did not even realize it had side effects. I have been having my whole head itching like crazy day and night and I never had that in 38 years! I have been having leg cramps and charley horses in my feet so bad. I have had severe pain in my right hip/thigh area so bad that I thought I was going to have to take myself to the ER. Sharp shooting pain down my leg into my foot and in a fog mentally to where my brain and mouth do not connect. The joint and muscle pains have been so severe that to walk from the car to the store has been almost impossible. I have not taken the dose last night and already the pain and cramping is lessening. I think I'll find another way to lower the cholesterol!!!
