@ruth36 If you determine it is your statin you may want to consider talking to your doctor about taking a break and trying an approach of less rosuvastatin and muscle strengthening.

I have tried darn near every way to treat cholesterol and it sounds like @suzva has been where you are. A slow approach with a variety of drugs, along with @jc76 recommendations is worth looking into. I eventually took 5mg of rosuvastatin two times a week. My doctor explained this particular statin stays in the body 3-4 days so this schedule provides continual protection in the body. I have also learned more is not necessarily better. It may be better to add a small amount of another medication that works a bit differently to a lower amount of statin that you can tolerate.

First things first, figure out what you are dealing with.

Have you talked to your doctor, or decided how to move forward with feeling better?
