I saw several doctors for all the symptoms, but so far everything they test came back normal. I had a brain
MRI, CAT
scan, chest X-Ray, blood tests, EKG, Holter monitor, and echo cardiagram. They want me to do EEG and also tilt table test next week. The gastroenterologist I saw recommended that I have a colonoscopy just in case, so I will probably do that in the next month or so.
Does anybody have any ideas what this could be and what other tests I need to get?
