Well finally found out that this test determines nerve damage? At least that what the official definition is! My Dr. says in his report "Am going to check and EMG of his right lower extremity to rule out active radiculopathy" I guess that answers my question? Does my pain that comes and goes (hourly almost) have to be "active" for him to get a positive result? Have tried here, web md, cleveland clinic and can't find the answer...does anyone else know of any site that might have the answer? Please pm or post if you could help out! thanx!
