I have a pimple on my crotch, which produces pus and blood. Is it an STI?

Hi, Welcome to icliniq.com.

I have seen the photo (attachment removed to protect patient identity). It looks like superficial folliculitis, which might be caused by bacteria or fungus. Shaving or wearing tight clothes that rub the skin can irritate the follicles leading to folliculitis. Most likely, this occurs when the improperly cleaned hot tub or swimming pool is used, wearing tight clothes, and using an infected shaving blade. You need to see a gynecologist. I also suggest you get your fasting blood sugar checked and get yourself tested for HIV (Human Immunodeficiency Virus)and other tests for STIs (sexually transmitted infections) if not tested before. Hope your query is answered, but if you still have any other question, please revert. Best wishes.
