I went to the doctor Friday after having a sore throat for about two weeks. He said it was infected and prescribed Amoxicillin 875 MG tablets. I have been taking two a day for two days. This evening, it feels like extra fluid, maybe saliva, is caught in between my ear and throat. When i massage my jaw line, and just under my ear, it helps, but still feels full of fluid. What could this be, and what should I do?
