I know how u feel. I don't have a lump in my throat but my tongue tingles and I have swollen lymph nodes .... and some ear aches a Dr said I was ok but I don't buy it.
Go to an ENT and have yourself checked out thoroughly to ease your fears (have them look at your mouth with a scope and check your mouth). Tell them your symptoms, about the hpv and your oral cancer concern. Be aggressive getting checked out thoroughly because they'll tell you to open your mouth and throw some antibiotics or acid reflux medicine at you without properly checking you out.
It typically takes 10 to 30 years for hpv to turn into cancer, but when the risk exists it exists. The only thing you can do now is get your self checked out regularly by and ENT and dentist.
Take care, try not to stress because that makes it worse and get checked out.
I hope and pray that you don't have cancer (me neither wink wink).
