Thanks to Colleen for inviting me in on this group. My son, daughter, and I all suffer from dysautonomia, and all of our symptoms are quite different. I was surprised to discover we all had the same underlying disorder. Clearly genetic in our case, but I have done lots and lots of research, and it seems that dysautonomia manifests differently in each person affected. We have seen numerous doctors and have done endless testing. We have finally come up with some pieces to the puzzle (though we are not sure yet how they all fit together).
