Rash after drinking sometimes

I’ve been since I was about 15. About 6 months ago I had a margarita and it made me get this rash so I thought it was the mango. Then it happened again from Michelob (which I drink almost daily). I took a week off drinking, then had a few beers and it was fine. As I’ve slowly started drinking again the rash has come back and it slightly worse. Has this happened to anyone else?
