I went to the Urgent Care once. It's not quite the same as the ER, but it was a same day emergency type of thing. Basically it was all just a waste of time. Basically the doctor just told me I didn't have MS and to go home. Although, in the bigger picture, I suppose that wasn't a waste of time, what with the reassurance at all. But afterwards I did feel guilty about it, since I sort of took an Urgent Care time slot away from someone who might have actually NEEDED it.In my experience, once you start giving in to "panic" appointments (same days, urgent care, etc), you start down a long dark path of quick fix anxiety. And that's never going to solve anything, because there is nothing that will ever cure BFS symptoms in one day. Even the stuff that has been reported to work for BFS (minerals, exercise, vitamins, counseling, more sleep, etc) takes a long time to start working. In my opinion, you have to approach treating BFS as a quote-unquote lifestyle change, instead of a disease. I don't think that an urgent care or ER visit will ever provide anything, other than reassurance.
