For anyone who still may be following this:

I guess I got over-confident again and over-reached; Or maybe I just had to see what would happen; Or I just got tired of not being able to eat normally; I was hungry and away from home and other food options. Or maybe it was 18 months of internalizing the gaslighting from doctors. Anyway, I ate a rotisserie hot dog at a food stand (with mustard). Within 30 minutes my nose ran and I began to itch all over. I should also mention that I was trying doxycycline for the rosacea (a known DAO blocker). One of those 2 things or the combination started the TAC headache. This is where it all started: I got a mysterious headache in 2018 after a period of ears ringing and itching, and my nose running. At that time I had no idea there was histamine in food, did not believe in food triggers for anything, and had no history of headaches.

The headache resembles trigeminal neuralgia, except the pain is not in my face. First my eye felt like there was something in it and electrocution like shocks or jabs started above my right eye and around my skull in that area. The tinnitus is loud and pulsatile. The jabs become more and more painful and closer together until it is excruciating and can only be stopped with a course of prednisone.

Thin blue lines (like ink marks) spontaneously appeared and then receded on the inside of my right arm. Probably a form a dermatographism -but alarming still. I got the usual gaslighting and dismissive manner from a medical practitioner on the other end of an urgent care video chat. I even got the condescending smile that one gets when they are certain that you are just having and anxiety attack and it's your "anxiety".

So I am recovering on prednisone but I learned a lot about the symptoms. I don't regret it.
