I just recently had a tooth extracted, the dentist did a root canal while infected and eventually had to extract tooth. I've been on antibiotics for 1 month now and just recently went to urgent care due to swollen lymph nodes in neck and under armpit.. So He also put me on an antiibiotic called augmentum for bacterial infection. I woke up this morning with my throat feeling like it is going to close and my tongue is very white and pus looking, I cant explain it. Should I call My doctor or dentist again.
