I've ruled out all the other diagnoses like lupis, mast cell, niacin, etc. an am convinced it's carcinoid because the flush is exactly as seen on internet video
. Because my flushes lasted at least 20 minutes from the first one, and because it's not just my face and upper chest, it's most likely foregut which is so much harder to diagnose. These last two + years have been so stressful. Please let me hear from you all as to your situation now. Thanks.
