I found that I have Histamine Intolerance and possible Mast Cell activation syndrome. I'm sad about another diagnosis ( Hashimotos and TED) But HAPPY to have found the culprit! Google Histamine Intolerance and Anxiety. You'll be amazed. All of my symptoms plus Vertigo, flushing, itchy skin, and rashes or hives.
Im On to a low histamine diet and some supplements recommended by my Functional doc. Praying it is resolved quickly. I'm already sleeping so much better!
