A trip to the ER: Blisters forming on mucous membranes (such as the inside of your mouth and lips) and/or elsewhere on your body could be signs of a serious reaction to a medication such as your antibiotic. Please look up Stevens - Johnson Syndrome for one example of many possible types of reactions. I recommend an urgent evaluation, preferably in the Emergency Department.

See Dr: Possible reaction to Bactrim (sulfamethoxazole and trimethoprim). You need immediate attention. Do not delay. Bactrim (sulfamethoxazole and trimethoprim) is not used for "rash on leg". When was your hip surgery? Biopsy of what? Why? There is much more to this than the information supplied.
