I developed BFS after having a cold. I am sure the cold caused the full body twitches because my mother caught my cold and she subsequently developed the twitches as well. As most of you know, these twitches can drive you nearly insane as they did with me. I would sit in a bathtub for the whole day just so I wouldn't have to feel them. I tried all of the medications. Klonapin and valium just knocked me out and didn't get rid of my twitches. I tried quinine, taking extra potassium/magnesium with no luck. I eventually settled on using Xanax just to be able to fall asleep as well as an SSRI. Again, these didn't get rid of the twitches but made me not care about them so much. I'm a 4th year medical student so I decided to look up real medical literature on the topic instead of relying on online forums. I have learned that if you have some kind of health problem, do not look online for information! Mayo clinic did a study following 121 patients with benign fasciculations and none developed motor neuron disease in life so RELAX (Long-term follow-up of 121 patients with benign fasciculations. Ann Neurol. 1993 Oct;34(4):622-5). 19 of the 121 described having either an upper respiratory infection or gastroenteritis up to a month prior to onset of the twitches. If I recall, 60 of the 121 said their twitches lessened over time (the paper wasn't specific as to if anyone had completely gotten rid of the twitches). In the discussion of the paper they describe the etiology of the twitches perhaps being a persistent viral infection of the anterior horn cells in the spinal cord (which are the cell bodies of lower motor neurons going to muscles). It also could be an inflammatory polyneuropathy, but I doubt this because I was on 12.5 mg of prednisone at the time of onset. So two months after onset, do I still have the twitches (which were ALL over by body happening about every 30 seconds)? Not really. I saw a case report published recently about a woman who had hypothyroidism and had full body severe benign fasciculations (Benign fasciculations responsive to gabapentin. Arq Neuropsiquiatr. 2007 Dec;65(4A):1015-7.). Even when euthyroid her twitches persisted. So she was prescribed neurontin (gabapentin) 300mg three times a day and her twitches stopped. I decided to give it a try. I started at a low dose and ramped it up to 300mg twice a day and within 3 days twitches were pretty much gone. The paper recommends 300mg-600mg three times a day and says this dose is safe. Neurontin has no addictive potential like the other stuff and is generally a safe medication to take. Side effects include drowsiness, thinning hair and peripheral edema but these are supposedly rare. I don't feel any drowsiness when I take it. I'm not saying this will work for everyone but it worked for me. I would recommend talking to your neurologist about it and give it a try, though you should realize that this medication is not FDA approved for this. In fact it's really only approved as a secondary medication for seizures but it's used for a whole host of things off label. It might only work for those of us who have a viral etiology as neurontin is a nerve medication, not one that affects the muscle membranes. Again I'm not a doctor yet so don't take my advice as officially medical.
