I stopped taking Crestor 20mg on doctors advice about a week ago, how long should I expect it to take my system to rid my body of suspected side effect? I have been taking if for over 10 years and have suffered increasing joint and muscle pains during this period, they have recently become unbearable. I'm a 69 year old male, and beside the escalating joint and muscle pains I am in pretty good health since my heart attack in 2003
