Rash issue: If the staphylococal infections (staph for short) is from a skin infection such use of Bactrim (sulfamethoxazole and trimethoprim) can be helpful if topical antibiotics are not useful. A skin rash is not uncommon from the Bactrim (sulfamethoxazole and trimethoprim)'s ingrdients (sulpha for example). Seek medical attention for such rashes before they might worsen.

Yes: Allergic reaction to sulfa antibiotics, Bactrim/Septra in particular is not that uncommon. Your description sounds suspicious for just that. I would see your doctor for this to determine the next treatment option for you. If this is an allergic reaction then you should avoid sulfa antibiotics in the future.
