My husband took statins for 2 years and we recently found out that proteins were spilling into his bloodstream. His leg muscle cells were dying He lost 25 lbs and became very weak. I thought it was age related..but soon found out it was a rate side effect of statins. His recovery is going to be a struggle as he could barely hold himself up. Im thankful for a great Dr who ran the right tests to discover this. He can never take that drug again. He barely gets through therapy now. But we are hoping over time he can regain his strength. His thinking was affected too. I thought he was getting dementia. But it was the drug
