Anything is possible, I personally cannot say I have this symptom. There are alot of things that can cause this, if you watch TV you will see ads for drugs that may help this, by which I mean it may be fairly common. I am currently fighting a nagging cold, sinus infection or whatever it is, although I do not think this is BFS related, I will be honest, I think everything else is. That is one thing I had a very hard time with early on is contributing every little thing that I felt to, what I thought at the time was ALS, now I do that with BFS, anyone else do that? Even a patient with ALS can still pass a kidney stone, or have a headache, or even get cancer. We have to deal with BFS and all the other goodies that come with the territory, and it is easy to get them mixed up. Postpardum, sorry I wandered but it is a good question, it just brought up some memories of myself tying everything to ALS, I am glad your question was whether on or not it was related to BFS, you are lighyears ahead of me on that one
