5 years of unbearable muscle leg pain. lots of meds prescribed to try to help relieve the pain but no relief. cpk is high. can a dna test help?

If your CPK-MM is: elevated (that's the portion of CPK that comes from skeletal muscle), then a much more worthwhile initial test is a muscle biopsy. Depending on the results of the muscle biopsy, genetic testing (including mitochondrial DNA) may be done to confirm certain diagnoses. Unfortunately, treatment hasn't kept up with diagnosis in many genetic disorders. Best wishes. Dr. Anne
