angular cheilitis,exfoliative cheilitis, white tongue, tested negative for HIV

As I'm writing this message I'm extremely happy cause I finally took the courage to do an HIV test and came out negative! My problem (exfoliative cheilitis, angular cheilitis, white tongue and later intestinal problems, red patches on throat not always hurting )started 8 years ago and I couldn't find any particular event related with this outbreak, althought all this started a month after I broke up with my girlfriend and we used to have sex without condom... And as you now if you search on the internet you will find that those symptoms may be related to an Hiv infection (my angular cheilitis extremely recurrent and persisting ). So now I'm super happy but I still can't figure out the root cause. I only managed to control all this with B vit and less sugar, but is still a mystery how all this has developed. What should I investigate next?? Bacterias? Dental problems? Thanks for your attention, Luca
