Lump in the groin?


Three months ago, I had unprotected sex with my partner but did not ejaculate inside.
Now, I have a bump in my groin area that oozed yellowish fluid after being squeezed, and it hasn't healed yet.
There are many fleas in my workplace, so I can't determine if it's a flea bite or a rash caused by HIV.
I don't have any other specific symptoms, and I haven't had a fever, but I did experience diarrhea for a few days in the morning.
Is it likely that I have contracted HIV?

Dr. Hu Ziren reply Oncology


The rash associated with HIV is typically systemic rather than localized, and since the bumps you described are purulent, they are likely just pustules and other subcutaneous tissue infections.
It is advisable to monitor the situation.

More Info


When it comes to groin bumps, there are several potential causes that could explain the symptoms you are experiencing. Given your description of a bump that exudes yellowish fluid, it is essential to consider a few possibilities, including folliculitis, an ingrown hair, or a sexually transmitted infection (STI) such as herpes or syphilis.
Folliculitis occurs when hair follicles become inflamed, often due to bacteria or irritation. This condition can present as small red or white bumps that may ooze pus. An ingrown hair can also cause similar symptoms, especially if hair is trapped beneath the skin. Both conditions are generally not serious and can often be treated with topical antibiotics or by simply keeping the area clean.

However, given your recent sexual activity without protection, it is crucial to consider the possibility of STIs. Herpes, for instance, can cause painful blisters or sores in the genital area, while syphilis can present as a painless sore (chancre) in its primary stage. Both conditions can lead to more severe health issues if left untreated.

Regarding your concerns about HIV, it is important to note that the symptoms you describe—such as diarrhea—are not specific indicators of HIV infection. Acute HIV infection may present with flu-like symptoms, including fever, fatigue, and swollen lymph nodes, but not everyone experiences these symptoms. The only way to determine your HIV status definitively is through testing. If you are concerned about potential exposure, it is advisable to get tested for HIV and other STIs as soon as possible.

In terms of your environment, you mentioned the presence of fleas in your workplace. Flea bites can cause localized itching and bumps, which may resemble other skin conditions. However, flea bites typically appear as small, red, itchy welts, often in clusters. If you suspect flea bites, treating your environment and using topical anti-itch treatments may help alleviate symptoms.

Given the variety of potential causes for your symptoms, it is essential to consult a healthcare professional for a thorough evaluation. They can perform a physical examination, take a detailed history of your symptoms, and possibly conduct laboratory tests to identify the underlying cause of your groin bump.
In summary, while your symptoms could be due to a benign condition such as folliculitis or an ingrown hair, the possibility of an STI, especially given your recent sexual history, cannot be overlooked. It is crucial to seek medical advice to ensure proper diagnosis and treatment. Additionally, practicing safe sex in the future, such as using condoms, can significantly reduce the risk of STIs and other infections.
