i have had a strange rash inside the buttocks for about 3 weeks now. its dry and some what red but not very itchy unless touched. Its also on my pubic bone, at first i thought it was an allergic reaction because im living in a very hot tropical climate plus the shaving. Im getting a bit worried that it might be an STD. What is it, i started taking antibiotics, im in cambodia and the medical service is pretty much non existant. What kind of pills should i be taking or cream? Please help.
