I am a 72 year old active women who has been diagnosed with osteo arthritis who has been sent to my cardiologist because of the my consistant high cpk reading. After electrograms, changes in cholestrol medication,( lipitor, crestor,), now on zetia my tests keep coming in high.Outside of my lower extremities aches, which I credit to arthritis, I feel fine. Both doctors, arthritis and cardiologist, keep drawing blood with these rates still climbing. After a year of this circle, and being a believer in preventive mediciene, my concern is should I be concerne?
