Hi,
I have small ulcers on sides of the tongue and it exists more than 9 months. These ulcers go away when i use an oral paste (oralT) and it grows again about 5 days after the day i used OralT paste. this ulcers are starting as a small white dot and spread around 1cm and it having white color margin around the ulcer. mostly this ulcers are grow sides of my tongue and they are so painful and give burning sensation. i had oral sex with a girl without having condoms im so much worry this ulcers are due to that unprotected oral sex. i had a HIV test(1,3,7 month after having oral sex) and herpese(3,7 months after having Oral sex) tests. result of all the test were negative. Im so confused why these ulcers not disappear from my tongue. appreciate if you can give advice to me. is this because of any STD infection.
