Hi, I had a sore throat 2 weeks ago - on the same day, I had extremely cold water, and unprotected oral sex. After taking throat lozenges and augmentin 875+125 for 6 days (2x day), my sore throat is gone, however, there is still some redness in my throat. Was wondering if it is normal redness in my throat, or if it's a symptom of an untreated sti. I can share photos to make things easier.
