Hi Dr. I had unprotected sex at the end of July. And 8 days later I developed mouth sores inside my lower lip and 3 days I developed a sore throat. I took Augmentin for the sore throat 4 days later and it went away. Now, it has been 3 months since possible exposure, and I'm still getting oral sores. I recently had a cold/flu like symptoms last week which lasted 3 days, but received the flu shot last month. I have never gotten mouth sore like this in my life. No oral sex just heterosexual. Herpes test was negative. I've had hep A,B,C vaccines. Are these signs of ARS symptoms?
