Painful Red Bumps on the Scrotum: Possible Causes - Dermatology

More Info

---

The appearance of painful red bumps on the scrotum, particularly near the inner thigh, can be concerning and may have several potential causes. Given your description of the bumps resembling acne but not being hard or associated with hair follicles, there are a few possibilities to consider.

1. Folliculitis: While you mentioned that the bumps do not have hair, it’s still worth considering folliculitis, which is an inflammation of the hair follicles. This condition can occur even in areas where hair is sparse or absent due to irritation or infection. The bumps can be red, painful, and tender to the touch.

2. Sebaceous Cysts: These are small, benign lumps that can occur on the skin, including the scrotum. They are typically filled with a fatty substance and can become inflamed or infected, leading to pain and redness.

3. Pearly Penile Papules: Although these are usually found on the shaft of the penis and not the scrotum, they can sometimes be mistaken for other conditions. They are harmless and do not require treatment.

4. Inguinal Hernia: If the bumps are associated with swelling or a bulge, it could indicate an inguinal hernia, where tissue pushes through a weak spot in the abdominal muscles. This condition can cause discomfort and requires medical evaluation.

5. Dermatitis: Contact dermatitis or allergic reactions can cause red, painful bumps. If you’ve recently changed soaps, laundry detergents, or other products that come into contact with the area, this could be a potential cause.

6. Sexually Transmitted Infections (STIs): Certain STIs can present with red bumps or lesions in the genital area. If there is any possibility of exposure, it is essential to get tested.

7. Lymphadenopathy: Sometimes, swollen lymph nodes in the groin area can present as painful bumps. This could be due to an infection or other underlying conditions.

8. Scrotal Abscess: An abscess can form due to infection, leading to a painful, swollen area. This would typically require medical intervention.

Given the variety of potential causes, it is crucial to seek medical attention for a proper diagnosis. A healthcare provider, particularly a dermatologist or urologist, can perform a physical examination and may recommend tests such as a culture or biopsy if necessary.
In the meantime, avoid any irritants, keep the area clean and dry, and refrain from scratching or picking at the bumps to prevent further irritation or infection. If you experience any additional symptoms, such as fever, increased swelling, or discharge, seek medical attention promptly.

In summary, while there are several potential causes for the painful red bumps on your scrotum, a thorough evaluation by a healthcare professional is essential to determine the exact cause and appropriate treatment.
