Hi, this is dr.syed minhaj ahmed, creatine
kinase elevation indicates that there is strain of the muscle and is not al a specific investigation which can lead us to a diagnosis.
However, joint pains
need to assessed clinically.What i would like to know is whether there is involvement of small joints of hand also ? with early morning stiffness
? in which case it may be a part of rheumatoid arthritis
with secondary myalgia affecting hamstrings.
