So, I very quickly got a toothache last Sunday week overnight where my face was very swollen. Went to dentist Monday afternoon and was started on antibiotics. She told me if the swelling didn't go down, go to a&e for IV antibiotics. Next morning swelling was much worse; couldn't open my eye so went to a&e, got one dose of IV and home again. Finished the abx on Sunday, was better but dodgy stomach which I'm assuming was from the abx. Now since last night, very sick stomach and face seems to be swelling again. What do I do??
