I don't know your age, but I am wondering if some of these muscle aches and weaknesses are age related, but the statins and perhaps other drugs make these issues much, much worse. I am 66 1/2 - started statin at 64 and suffered increasing pain and weakness and cramps that progressed over 2 years. I eventually got 90% better when I stopped. Everyone noticed my decline is so many areas of my life in my statin years - couldn't do yoga, pick up grandkids, walk up stairs or get out of bed or the car without terrible pain. These are not little things. Quality of life issues big time.
