Lisa - those results are saying that you do have a myopathy and a muscle biopsy is needed to delineate which myopathy it is. When they do the muscle biopsy the doc can tell if it is metabolic, inherited or inflammatory, that way the treatment will reflect the type. Most of them are treatable except the inflammatory myopathy inclusion body myositis. But, they are an illness that will have to be treated for life, hopefully off and on and not permanently. Hope this helps some.
