A red bump on the foreskin?


Last week, while taking a shower, I noticed a large red pimple on the foreskin near the base of my penis.
At first, it felt slightly painful to the touch, similar to an acne pimple.
I thought it was just a regular pimple that would go away on its own, but it hasn't disappeared yet.
It seems to have faded a little to a dark red color.
Doctor, what could be happening? Will it eventually go away, or can I buy something over the counter to apply?

Help me: It is highly recommended that you seek medical attention for diagnosis and treatment as soon as possible.

When it comes to a red bump on the foreskin, there are several potential causes, and understanding these can help you determine the best course of action. The bump you described, which initially felt like a pimple and was slightly painful, could be due to a variety of reasons, including folliculitis, pearly penile papules, or even a sexually transmitted infection (STI) such as herpes or genital warts.
Folliculitis is an inflammation of the hair follicles, often caused by bacteria or irritation. It can present as red bumps that may resemble pimples and can be tender to the touch. This condition is usually self-limiting and may resolve on its own, but maintaining good hygiene and avoiding irritation can help speed up recovery.

Pearly penile papules are small, harmless bumps that can appear around the corona of the penis. They are a normal anatomical variant and do not require treatment unless they cause discomfort or anxiety.

On the other hand, if the bump persists, changes in appearance, or is accompanied by other symptoms such as pain, itching, or discharge, it may indicate an infection or another underlying condition. In such cases, it is crucial to consult a healthcare provider for an accurate diagnosis and appropriate treatment.

In terms of over-the-counter treatments, if the bump is indeed folliculitis, applying a topical antibiotic ointment like bacitracin or Neosporin may help prevent infection. However, if the bump is due to an STI or another serious condition, self-treatment may not be sufficient, and professional medical advice is essential.

It is also important to avoid squeezing or picking at the bump, as this can lead to further irritation or infection. Keeping the area clean and dry is vital, and wearing loose-fitting underwear can help reduce friction and irritation.

If you find that the bump does not improve or worsens over time, or if you experience additional symptoms, it is advisable to seek medical attention. A dermatologist or urologist can provide a thorough examination and may perform tests to determine the exact cause of the bump. They can also prescribe medications or treatments that are more effective than over-the-counter options.

In summary, while some red bumps on the foreskin may resolve on their own, it is essential to monitor the situation closely. If there are any concerns about the nature of the bump, especially if it persists or changes, consulting a healthcare professional is the best course of action. They can provide a definitive diagnosis and tailored treatment plan to ensure your health and peace of mind.
