Atorvastatin
"At age 48 and good health, I took Atorvastatin/10mg for 1 year without symptoms.  It lowered my bad cholesterol.  Near the 1st year, I began experiencing significant/unusual leg weakness and knee pain when standing from a kneeling position.  It got to the point that I always needed to brace myself on the sofa or coffee table when getting up after playing with my dog or toddler son.  Rising from my desk required a push on the desk top.  Then weakness and pain to my finger/shoulder joints and a "forgetfulness."  Overall, I felt "Rickety."  My MD said to stay on it.  I decided otherwise and went off cold turkey one day.  I've been off 2 years and I feel normal again, except for residual and reduced effect on my shoulder and hands."
