I also had severe muscle pain due to statins. I took the OneOme test, https://oneome.com/ and learned that I carry the SCL 101B gene and it is associated with statin induced muscle pain and myalgias. Your Dr. can order the test. Mayo was one of the early partners. I not only learned about statins, but also about many other medications that I can't tolerate. It has been invaluable for my medical team and helps us select medicines that help my autoimmune conditions, and avoid adverse side effects. Wishing you success with your medication and wellness journey.
