I have had a tonsil infection for over a year. Yes, a year. I just recently enrolled in health insurance. I have been on 4 different antibiotics over the course of the year. Amoxicillan, Cephalexin, Penacillan, and a liquid that I had to swish and swallow. None of it took it away. Now, the tonsil on the right side has turned black and I have white patches in my throat that are circled with a red line.
