Red Bumps on the Scrotum: Causes and Concerns - Urology

More Info

---

When it comes to red bumps on the scrotum, there are several potential causes that could explain your symptoms. Given that you have noticed several red, swollen areas near the left side of your scrotum that are slightly painful to touch but not itchy, it is important to consider a few possibilities.

1. Folliculitis: While you mentioned that the bumps do not have hair in the center, folliculitis can still occur in areas where hair follicles are present. This condition is characterized by inflammation of the hair follicles, often due to bacterial infection. It can present as red, swollen bumps that may be tender to the touch.

2. Sebaceous Cysts: These are small, non-cancerous lumps that can occur under the skin. They are usually painless but can become inflamed or infected, leading to redness and tenderness. They often feel like small, soft lumps under the skin.

3. Inguinal Hernia: Although not a skin condition, an inguinal hernia can cause swelling in the groin area, which may be mistaken for skin bumps. This occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles.

4. Contact Dermatitis: This condition arises from irritation or an allergic reaction to substances that come into contact with the skin, such as soaps, lotions, or laundry detergents. It can cause redness and swelling, although it typically also presents with itching.

5. Infections: Bacterial or fungal infections can lead to localized swelling and redness. Conditions like jock itch (tinea cruris) can cause red, inflamed areas in the groin region, although it usually presents with itching.

6. Sexually Transmitted Infections (STIs): Certain STIs can cause lesions or bumps in the genital area. Even though you mentioned no recent sexual activity, it is still important to consider this possibility, especially if you have had unprotected sex in the past.

7. Pearly Penile Papules: These are small, harmless bumps that can appear on the penis or scrotum. They are normal anatomical variations and do not require treatment.

Given the variety of potential causes, it is crucial to seek medical attention for an accurate diagnosis. A healthcare provider can perform a physical examination and may order additional tests, such as a culture or biopsy, to determine the exact nature of the bumps.
In the meantime, avoid touching or picking at the bumps, as this can lead to further irritation or infection. Keep the area clean and dry, and consider using mild soap without fragrances or irritants. If you notice any changes, such as increased pain, swelling, or the development of new symptoms, seek medical care promptly.

In conclusion, while there are several benign explanations for red bumps on the scrotum, it is essential to consult a healthcare professional for a thorough evaluation and appropriate management. Early diagnosis and treatment can help alleviate discomfort and prevent potential complications.
