I felt the same way. I tried all the oral Statins and ALL gave me muscle cramps. I was offered Repatha when it first came out and thought like you. But my self and my doctor agreed to give it a try and low and behold no issues at all. I understand your concern but Statins have along with all drugs a whole list of POSSIBLE side effects. If you try it and it works you will be glad you used it to lower your cholesterol. Personally, for myself it was worth the gamble. Best of luck and keep us posted on your progress.
