Can dysautonomia cause brain to feel swollen (along w/ lightheaded).the swollen feeling is so bothersome!also have ctd.negative brain mri.normal sx?

Follow up: Dysautonomia can effect many body symptoms but not usually one. I recommend you discuss this symptom with the provider who obtained the mri.

Dysautonomia: This is a very non-specific term that could mean a number of things. You should consult a neurologist and a rheumatologist to make sure you are getting the optimum management and not missing anything.
