I took zetia for a 30 day period and found that I was having upper arm weakness and weird sensations in the same area. I would no longer take Zetia. A number of months later I ruptured my right bicep while lifting a frying pan in the kitchen. I thought the Sensation I felt when it occurred was from a muscle cramp and found out later the bicep rupture. 4 years while lifting my desk blotter to slide dust & small debris left frok roof replacement on my office, I ruptured the left bicep muscle. Now years later I continue to have upper arm and shoulder ruptures without doing anything out of the ordinary. I don t lift weights or anything like that. I feel this has all been caused by the Zetia I took. Have other people been having this similar reaction?
