Hello, CRP levels usually increase when inflammation is present somewhere in the body. If you can t recall any possible inflammation (including teeth problems, inflammatory papules etc) then it could be even a subclinical viral illness. Rheumatoid arthritis also causes a CRP level elevation but this is not specific or diagnostic. Such a slight elevation is not clinically that important most of the times. SGOT elevation has to do with muscle problems (including the heart muscle) and injuries but it s not that specific either. Have you checked for high creatinine phosphokinase? This is a muscle enzyme that increases in muscle inflammation or destruction. You haven t provided enough clinical information to help me judge whether a muscular problem is likely or not. Levothyroxine is not supposed to affect them unless you re taking too much and your TSH is almost undetectable. I hope I ve helped! If you d like further information, please provide more details about your condition including symptoms and other laboratory testing you might have done. Kind Regards!
