Sometimes it can be hard to tell if the ‘tiny brown skin bump’ is skin pigmentation change on a scar, a new mole or a wart and standard practice is for the doctor to ask you to come back if it doesn’t go away so can check it again. You could also go to your local STI clinic for a second opinion. The doctors and nurses at an STI clinic are used to looking at genital skin and can tell you if its a wart or not and offer treatment if needed.
