Why does the crotch bump recur in the same spot at age 20?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I am a 20-year-old female who weighs 224 lbs, and I am 5.4 feet tall. I have what looks like a pimple on my crotch. It keeps coming back in the same spot and produces white pus and a lot of blood. Is there a chance I have an STI (sexually transmitted infection)? I have had it since before I became sexually active. I always use a condom. I have attached a photo of the pimple.

Hi,

Welcome to icliniq.com.

I understand your concern.

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 questions, please revert.

Best wishes.
