I recently had the gastro bug (18 July ish) and in the last weeks I have suddenly started having allergic reactions to everything I eat. My symptoms are red flushing, eye swelling, eye eczema, itchiness and these small water blisters that come up on my hands during a reaction. I have had some histamine intolerance issues in the past, but I have never experienced anything like this before. Blood tests came back normal and the doctor didn’t know what was wrong. Has anyone has something like this before and could give some advice? Thanks in advance.
