My doctor put me on amoxicillin which slowly helped. A few days after I finished the ten day treatment, my post
and sore throat came back. It lasted 2-3 days, then went away. A few days later, it was back, and worse. I went to the doctor again, who said it looked like I had a throat abcess. He gave me omnicef and medrol pack. The sore throat and post-nasal drip got better after those meds, and again, a few days after I finished them, it was back.
