Hi, Due to a tooth infection I was prescribed Apo-Amoxi Clav 875/125mg twice a day for 7 days and a painkiller every sixhours , Ketorolac Tromethamine 10mg to bring down infection before a root canal could be done. I am now on day 6 of antibiotics and my ear lobes are hot, swollen, extremely itchy, rash developing on the back of my neck. I wondered should I go see a doctor or is this a common reaction to antibiotics?
