I had normal cpk aldolase esr repeatedly and other blood normal along with normal emg/ncv. normal skin biopsy. can you still have a muscle disease?

Difficult: This question (and the related one you asked) are very difficult because i don't have enough data. The short answer is 'yes, maybe', but normal CPK and aldolase rule out a lot of possible muscle diseases. You may need a spine MRI to evaluate possible spinal cord disorders, but your physicians (especially i hope a neurologist) can best judge the nature of your problem and how to investigate it.
