There's a CDC site you can look into, although you may have already gone there (?), anyway here it is in case you haven't visited it:
I have HPV, and I've experienced sore throats and tonsillitis throughout my entire life ( since early childhood, way before the HPV), but yet to have any oral cancers thank goodness. I envy you because you have found a doctor who is willing to remove your tonsils, mine refuse to :( so I get stuck taking antibiotics and pain pills...
You should get screened/tested for HPV by your gynecologist, it's very easy and simple, and you can be in & out of the dr.'s office within a 1/2 hour tops. It may help ease your mind from worry.
Take Care and Good Luck
Hi, you're welcome
Yes, actually I have had the white tongue issues every time that I've had tonsillitis. I've had so many throat problems ( bouts of tonsillitis/ strep throat) in the past few years, that the pharmacists know me by first name now. Anyway, maybe ask your doctor about what's going with your tongue, and ask about antibiotics for your tongue issues, but if there's not any infection going on, they probably won't prescribe antibiotics. Some people believe that discoloration of the tongue, is a sign of stomach or digestive problems.
If you find out what the cause is, let us know!
Take Care :)
