Thank you for your question regarding your genital lesion. It is difficult to answer your question without being able to see the bump in person. Therefore, it is very important that you visit your Ob/Gyn, who can perform a physical examination and visually inspect the area. That being said, there can be several reasons for genital bumps. STDs are one possibility, if you are sexually active and not using protection. Genital warts
can look like small bumps the color of your skin or may be cauliflower-like in appearance. Herpes also may appear as bumps or vesicles, fluid filled round blisters that can burst and leave painful ulcers. There are also benign conditions that can appear as a bump in the genital region. For example, there are glands in the vaginal area that are can be prone to developing into cysts such as Bartholin's glands; these are two pea sized glands near the vagina which are responsible for producing vaginal lubrication. Often, cysts can be treated with warm compresses and time will lead to clearing of the lesion. Other times, the cyst may become infected and in those situations, may require opening and drainage. You should talk to your doctor
who can help determine the best course of action for you.
