Hi, I was having syncope episodes and falls (sometimes with serious injuries) for 7 years among other things that gradually developed with it. Tested for everything no results came to mayoclinic. They did a very thorough evaluation that took 2 years (I don't live near there.) They found the real dx but not going to specify because that's not the point. Point is getting thorough competent evaluation as it could be tons of things and I'm not a dr. Just find the right hands and get in them. Wishing you all the best. Marnee
