Amoxicillin / clavulanate
sinusitis
"I was prescribed this for 10 days for an ear infection,  my first 2 days I just felt nauseous but I ate a heavy meal and noticed that did help BUT for the past 3 days I've been having severe headaches and I still have 5 days to go. I think I'm going to stop the medicine it's not worth the pain! My ear does feel better though!"
