Sure and thank you. My fiancee went to the emergency room with what appeared to be a boil on her face. she had a staph infection several years ago when she was in an institution. It was in her underarm . The boil or cyst was about golf ball sized. they lanced it removed the cyst sack. Gave her a shot and 10 days of bactrim and another antibiotic. That was Wednesday, today she reports she is having pain when swallowing . food, liquids, hot or cold and taking the medicine is unpleasant. She says the pain is akin to when you get food or liquid while breathing. very uncomfortable. she has a high tolerance for pain, so the fact that she mentioned it is pretty significant.
