I am curious if your reaction to Repatha has subsided and I certainly hope that it has. Your experience sounds exactly the same as my husband's. Thirty plus years of severe pain and muscle loss due to statins. Second dose of Repatha and he can hardly lift his arms or even stand up. This particular reaction has continued for the past two months. There is not one doctor willing to attribute this to the many years of statins and then Repatha. It is quite frustrating. I do hope you are well and if you have had success with any particular specialist or treatment in overcoming your symptoms, I would love to hear from you. Thank you.
