Well, you should go to the doctor and be checked out. You could have a strep infection. You could have irritation from post nasal drip from your sinus issues. It could be irritation from allergies, a cold, a run of the mill sore throat. It's not necessarily an STD - lots of things cause an inflamed throat.

Go to your primary doctor to put your mind at ease.
