Hello, this may not be a thyroid question but I was hoping I could extract some of your expertise in endocrinology. I've been experiencing symptoms which including early heartbeats, depersonalization syndrome with panic attacks, and a stong and distinct feeling of butterflies in my stomach for no reason. I'm often left with a bad headache after a severe period of symptoms. I have never been a weak person, in fact I got a pilots lisence at 18 and used it regularly up until a few years ago...point is those require yearly medical exams and I was fine. Never been a big doctor person either. It seems like that anything which brings up my adreneline or metabolism makes my symptoms distictly worse. I think I finally realized this after exercising the other day, my dersonalization became severe hours later, as I was laying in my bed I felt intense butterflies in my stomach that makes the DP worse, and my stomach violently contracted and I regurgitated my food into my mouth. When I exercise, I'll be in a worse state of mind the rest of the day, quite the opposite of what you'd expect. This is probalby why I subconsciously went many months of being very inactive and indeed I felt much better during this time, but it made me gain alot of weight. What can I do, I have had all the usual blood tests including thryroid, liver chemistry, CBC, CMP, stress test, echo, brain MRI, cortisol spot check in the ER (late evening). Any ideas on this?
