I am taking a sulpha drug for a bladder infection - just started it yesterday after going to urgent care. I woke up this morning to find my eyelids swollen, forehead some, cheeks below my eyes, and face in general feels swollen. Should I start Benadryl or go back to Urgent Care? And I can't go back to the same Urgent Care I went to as they are closed on Sunday...it would have to be a different one (in a town 45 min. away).
