No worries. I actually thought I had MCAS but I didn't mention it because it's not really easy to diagnose and because it's not really necessary to confirm. I had an "immune system test" by everlywell and it said a few things but said, interestingly, wheat but not gluten. I tested it. Wheat makes me sick, primarily asthma and GI stuff, barley and rye do not. I used to think I was gluten intolerant but I'm not technically. I say I am because it's easier to explain to a waiter or acquaintance than the true details. Eat what makes you feel good and avoid processed foods is a good model for health.
