Hello all. This is my first post, though I've been lurking for months. My question is simple: does BFS (or its analogous conditions) progress over time? From what I've read here and elsewhere, the symptoms/signs should be relatively stable over the long term, arising then fading due to a variety of factors. Some of my symptoms fit that pattern, but several do not. Since this started in Dec. 2000 I've had some symptoms get worse or occur more frequently. E.g.: my legs are weaker now, and often I go weeks or months walking with a shambling, shuffling gait, using a cane to avoid falling and injuring a foot or knee. So does this happen with BFS? Have any of you seen or personally experienced this kind of progression? The docs I've seen aren't sure what's going on, though a lot of possibilities, from myasthenia gravis to somatization disorders, have been ruled out. Thanks for reading.
