At the end of January, I had a one night stand with an ex girlfriend. A few days later, I came down with the worst sinus
infection and sore throat Ive ever experienced. I went to the Dr right away, was proscribed antibiotics, and the problem seemed to resolve itself. Then, a month later, I was back at the Dr. with the same issue. Once again, 10 days worth of Keflex was proscribed, and I went on my way.
