I have elevated Creatine phosphokinase (CPK) and Sed rate (erythrocyte sedimentation rate) along with muscle soreness and pain?

Elevated CPK and Sed Rate along with muscle soreness and pain.

For the last 11 months I’ve had varying degrees of muscle soreness and pain. My CPK rate was 1276 last July and has been between 300-700 for the last 10 months. My peak sed rate was 35 and has never gone below 20 in the last 11 months. 35 year old male. Had electro muscle test that came back negative. It’s not debilitating but it’s annoying and painful on some days.
