I have a neurological disorder (recently diagnosed at Mayo) and have had swallowing difficulties for a number of years. At Mayo, they determined that although I do have a neurological disorder, the swallowing difficulties are due to a mechanical problem. They did a fluoroscope exam to determine this. I think my neurological disorder may exacerbate the problem, since stress seems to worsen the problem, and it gets worse as I tire, but it seems to be mostly just the mechanical/structural problem causing most of my difficulty.
