I took some antibiotics 3 months ago for a UTI and noticed a bright red, hand-sized rash appear under my left breast area. No bumps - just a smooth red rash that itches mildly sometimes and acts like a sunburn when touched. It stayed for 3-4 days and slowly disappeared.
This week I got another UTI (that's a whole different subject) took some of the same antibiotic, and now have the same rash, same spot. Any similar experiences, or more information on allergic reactions to this medication?
