Tell me all about HPV !!

Im trying to get an understanding of HPV so please please feel free to share your stories. During my pregnancy my doctor detected abnormal cells on my cervix, i had a coloposcopy done and it was confirmed that i had some minor abnormalities that she said could pass once i had my baby but she wouldnt check until after he was born. Whew ! I never got to see her again nor did i get checked again.. I dont have insurance any longer and at the time i had no way to get there.. Skip nearly a whole year later... I started experincing issues with my throat it started off as a cough (i dismissed it because i do smoke weed occassionally) but then the symptoms subsided and came back with a force... Ive been to several doctors and they all say im fine i just have some post nasal drip and possibly a wisdom tooth infection.. Im so afraid because in the back of my throat its pretty clear its cobblestone (lumpy back of the throat) and also two red nodules that are painless... My teeth are very sensitive as well im so afraid it may be HPV. Googling shit doesnt make it any better im so afraid i have been with the same partner forever how is this even possible...? the other symptoms went away but i still have cobblestone in my throat the doctor called it lymphatic tissue saying it would eventually go away but its been two months its still there
