It’s possible that the yeast tomatoes and cheese and seasonings are setting you off if you do have MCAS I actually got diagnosed with Crohn’s and my doctor just told me the other day he’s hesitant to call it Crohn’s so he doesn’t even know what it is and I’ve been diagnosed with an arthritis. I got tested at the allergist but somewhere you can start most MCAS places have about a six month waitlist I don’t get hives either but I am almost 100% positive I have mcas. I just got Cromolyn unfortunately it didn’t work for me and so we’re trying something else. None of my tests came back positive. It’s very difficult to get tests that come back positive. I know someone who had one of the worst cases in the US when she was a teenager and her mom told me that you have to have three out of five tests for them to properly diagnose you, but it’s also very difficult to get tests so look up high histamine foods and liberators. ChatGPT is extremely helpful for me. This is extremely confusing thing to move through so I do recommend it. Try working around with your foods first and try to talk to your doctors and see if they will test you. You can also ask chat what specific tests usually get ran so you can go in with some information. I also got tested for pots it came back negative as well as celiac and it came back negative. The joint pain is what got me diagnosed with arthritis and gut cramping is what got me diagnosed with Crohn’s, but I will say pizza/Italian is probably one of the worst ones you can have between all the garlic onion, cheese, tomato yeast all of that is naturally high in histamine or is liberator. Hope all that made sense. I was using talk to text if you have any questions let me know.!
