@isnotanxiety. After a few months of being on this site, it's hard for me to keep people straight. Didn't you say something in one of your early posts about coming in contact with someone you thought had Covid about the time your symptoms appeared? This could well be the cause of your SOB, etc. I've gotten interested in the underlying role histamines and amines play in causing health problems and have it on my to-do list to read more about it and the anti-histamine diet to reduce inflammation. It might be interesting and valuable to you to look at what you are eating and drinking and eliminate those things that have have histamines and amines to see if that helps. Maybe the article you referred to that mentioned food said something about that. We're benefiting from the knowledge you are finding and sharing with us as you try to understand what's going. Thanks! Take care. Nancy
