Heya Roblynn, please know that I was by NO means implying BFS + stiffness = Isaac's syndrome. You're right, there's a host of things that cause stiffness, including just living. I thought since you posted your concern a out it on the forum, you felt it was related to BFS. Stiffness just isn't one of the many things I've experienced with whatever it is I'm dealing with. Personally I don't like the term BFS because it puts us all in one group and there are numerous other conditions that cause peripheral never hyperexitabilty. I guess I'm just not convinced we're all dealing with the same thing so I continue to look for answers, probably to my own detriment. My other DDx that my neuro gave me aside from BCFS included late exposure to toxicity and restless leg syndrome. Of course when I asked her why restless leg syndrome when my symptoms are diffuse, she didn't have an answer. When drs see a normal EMG, MRI of CNS, and blood work, you get the BFS Dx, which is the same thing as, "I dunno." And unless we force our drs to explain why it's not something else, the other conditions that cause perpherial nerve hyperexcitabilty are still on the table as far as I'm concerned. That's just my perspective, tho.It would be interesting for this forum collect statistics on why people leave it. Is it because people later receive another Dx, twitching resolves, no longer require the support, etc. This forum has been around since, what, 2002. Why isn't it choke with hundreds of active users as oppose to only few? The forum seems to be laden with cohorts of users that change over time. Where are these BFSs going? Sorry...I'm ranting now (not at you) probably because I'm frustrated. I hope whatever is causing your stiffness clears up.
