I do have dodgy skin, in that I react to cosmetics and stuff. But recently I have had the most incredible itchy hives. On Dr Google one of the side affects is hives. My GP says no such thing. Has anyone else had a reaction to it, and is there anything I can take instead of Met? I've stopped taking it and my skin clears, literally one tablet and a short time later my skin complains with huge bumps and itching.
