I,too, have had this problem for 2 1/2 years and have had similar tests (even the EMG, which showed nothing).I've had every treatment known to man for this condition, with NO HELP WHATSOEVER. I'm at my wits end and don't know where to go from here. I'm, for the most part, immobile. Wish I could give you more encouragement. Seems drs, these days, don't have answers to lots of things.
