I have done HIV elisa & HIV rapid test after 1 Year of sexual vaginal intercourse and it was negative so do I need to worry further. Is there any chance of HIV infection in future. I was worried because I m suffering from ulcer on gums from last 8 months. But this gums is not paining nor it is burning. I showed to many doctors including ENT specialist they told it is a heat of stomach. I also took some allopathy medicine & now I m taking homopoethy but no improvement. Doctor told heat is too much in my stomach and it will take time to heal Please help me.
