About 3 months ago I engaged in oral sex with another boy (I am not gay, but every now and then I play around with this boy, so it doesn't happen very often at all maybe once a year). No semen ever entered my mouth. A few days later I got really sick, sore throat, fever, and eventually lost my voice for a few days. When I recovered, my voice sounded different.. not hoarse per say, but just different, and was noticed by a few others.
Ever since then, I could feel that my voice has not recovered. While my nose is not that stuffed or runny, there is always mucus present. It has gotten harder to swallow, and I can't drink liquids as fast as I used to. I can easily tell that my left part of my throat (larynx?) is completely swollen (but it doesn't hurt). Lastly, people have pointed out that I have become a heavy snorer (I'm assuming due to the swollen throat as I am extremely thin) and my mouth is extremely dry when I wake up.
I do not smoke anything, or drink. Is there a good chance that this is HPV? If so what percentage chance? Thanks.
