so crazy but I have had this happen about 3-4 times in my life, no trauma, no new foods, but my
lip swells up like a grape just on one side. The
lip is usually mildly itchy, but nothing too bad. I chocked it up to inappropriate cytokine/ histamine response, both cause swelling and mild itching. Maybe I was eating too aggressively, bumped my lip with the fork and didn't notice but my body did.
