I am on my 4th day of sulfameth/trimethoprim 800 mg @ 2 x's a day along w/ another medicine, I have bronchitis & staph (from an ingrown hair on my inner thigh OUCH!!) This is the second time I've had to take this medicine in the past 2 months & this is the second time I've had a sore throat & swollen vaginal area (labia mostly) i'm use to it swollen at times after "personal time" w/ my husband, but this is ridiculously swollen! Anybody had that symptom before???? And is that normal???
