Question answered:01/04/08
GP Notebook reports that the normal range for CK “are 24-170 Units/litre in women, 24-195 in men” [1]. Within that section they report that raised levels can be due to strenuous exercise [2] and intramuscular injections [3].
The medical website Wrong Diagnosis categorises and offer potential causes of muscle pain [4]. As we are unsure of the type of muscle pain experienced we recommend you view the site via the URL below.
Muscle pain could also be a side-effect of the anabolic steroids [5] and rhabdomyolysis has been reported in anabolic steroids users [6, 7]
The question was reviewed by our medical director who states:-
The grossly elevated level probably indicates acute inflammatory myopathy and the most likely cause is steroid induced rhabomyolysis – I refer you to the emedicine chapter on the subject [8] as this patient probably requires urgent full metabolic work up
