Hi Steve! Badhbt is correct, regarding science and answers. (took me a few years to grasp that there may not always be answers) I too see Dr. Thyerlie, and will state she is incredible and very respected and missed from the UW. She specializes in autonomic nervous system, and I believe this is they type of neurologist you want to see, one that understands this complex system. The TTT at the UW is also one you should look into if you are wanting diagnosis or rule out Dysautonomia. I had mine in January at the UW, great tech and staff, but not an easy test if you have Dysautonomia... (went through two and half years of heck trying to get a diagnosis, it was very frustrating, and not uncommon with Dysautonomia and it's sub types. at onset of illness it was thought I had a lymphoma and underwent so much testing/biopsy regarding) Dr. Thyerlie is fantastic and hope you can consider to see her, if anything a consult? You mention going to Europe ... She is originally from Germany, educated and has trained there and in UK, additionally to here in USA. She brings a big background of experience and education. Which is something I highly respect. Regarding that flushing? Can't say which specialist is best, but do read about folks with Dysautonomia that get this from different reasons. I have Skin Marbling, which has to do with the blood vessels and blood pooling. (red spider web like patterns with purple/red and yellowish hue to legs, purple/black feet/ hands) This was diagnosed via Neurologist. Hang in there. You've come to a great forum with incredible information and amazing members!
