I am 46 years of age and have been treated for benign hypertension since age 20 with antihypertensives. I am currently taking a combination of lisinopril 40 mg and metoprolol 100 mg once daily. For the last ten years or so I have taken lipitor 10mg. I am 6'00 and 275, I have not consumed alcohol for over three years nor any form of tobacco for over a year. In spite of my weight, I am a "half marathoner' and just recently got into Cross-Fit...Cross-Fit has made a huge difference in my muscular development. I recently had routing labwork done, and all of my CMP, Lipids came back withing expected range. My CK level though, is 432...what the hell!?! I have no symptoms other than the results of the lab...should I be worried.
