More Info


When you notice a red oval bump on the scrotum that measures approximately 1.5 cm in length and 0.3 cm in width, it can understandably cause concern. The fact that it is painful when pressed but not itchy or painful otherwise provides some clues about its nature. There are several potential causes for such a bump, and understanding these can help you determine the appropriate course of action.

One common cause of a bump on the scrotum is a sebaceous cyst, which is a benign growth that can occur when a sebaceous gland becomes blocked. These cysts are usually painless unless they become inflamed or infected. Another possibility is a folliculitis, which is an inflammation of the hair follicles that can lead to small, red bumps. This condition can be caused by bacterial infections or irritation from shaving or other grooming practices.

A more concerning possibility is a sexually transmitted infection (STI), such as herpes or genital warts, which can present as bumps or lesions on the scrotum. Additionally, conditions like epididymitis, which is inflammation of the epididymis (the tube at the back of the testicle), can also cause pain and swelling in the scrotal area.

Given the variety of potential causes, it is important to seek medical evaluation to determine the exact nature of the bump. You should consider seeing a urologist, as they specialize in male reproductive health and can provide a thorough examination. A urologist will be able to assess the bump, take a detailed medical history, and possibly perform tests such as an ultrasound if needed.
If the bump is suspected to be related to a skin condition, a dermatologist may also be appropriate, especially if there are concerns about skin infections or other dermatological issues. However, starting with a urologist is advisable since they can address both urological and dermatological concerns related to the scrotum.

In terms of next steps, it is recommended that you schedule an appointment as soon as possible, especially if the bump changes in size, color, or if you develop additional symptoms such as fever, increased pain, or discharge. These could indicate an infection or other complications that may require prompt treatment.

In summary, while there are several benign explanations for a red bump on the scrotum, it is essential to have it evaluated by a healthcare professional. A urologist is likely the best first point of contact, but if necessary, they can refer you to a dermatologist for further evaluation. Early diagnosis and treatment can help alleviate any discomfort and address any underlying issues effectively.
