I read posts a lot but don't respond very often. Gabapentin and EMGs caught my interest here. I did receive a Cramp Fasciculation Syndrome diagnosis 2 years ago following my EMG which showed "showers of cramp potentials" for no reason and had the EMG staff baffled. This was the final proof the neurologist needed since everything else fit -- visible fasics or twitching in the calves, extreme exercise intollerance, muscle stiffness and tightness, the pins and needles, shooting pains, etc.That was the EMG part. For two years prior to the diagnosis, as the functionality of my legs decreased from being a competitive athlete down to being able to walk, I'd tried endless things -- Physical Therapy, steroid injections, NSAIDs, Anti-inflammatory diets, Orthotics, Chiropractic Adjustments, acupuncture (although the calve muscles were so tight the needles wouldn't go in), homeopathic remedies, vitamins, etc., etc.I tried Gabapentin after the diagnosis and it was the first thing that had any effect in two years. There was an immediate loosening of the muscles and the pins and needles and shooting pains went away. The visible twitching went way down but did not go away. The twitching itself didn't bother me at all, though, just the tightness, muscle tearing and exercise intollerance. I'm one of the high dose people mentioned in the string at 2,400 mg a day. I've made a systematic experiment of medication combinations over the last two years trying nearly all the meds associated with CFS or BFS including the anti-epileptics, benzos, muscle relaxants, SSRIs and SNRIs, etc. I'm not going to go into that now but follow up with me if you'd like more on that.Anyway, I'm at the very end of that experiment. I've regained about 75% functionality with different med combinations, with Gabapentin as the main one. I can't sprint but I can do about everything else. Sorry about such a long post.
