Skin redness and swelling?


Recently, the skin on my scrotum has become red, swollen, and painful, but it is not itchy.
There is also white pus in the center, and it feels hard to the touch, along with the appearance of small red spots.
Could this be eczema?

More Info


When it comes to redness and swelling in the scrotum, there are several potential causes that should be considered. The symptoms you describe—redness, swelling, a hard texture, and the presence of white pus—could indicate a variety of conditions, and it is essential to approach this with caution.

One possible cause of these symptoms is a skin infection, such as folliculitis or a bacterial infection. Folliculitis occurs when hair follicles become inflamed, often due to bacteria. This can lead to red bumps, pus-filled lesions, and discomfort. If the area feels hard, it could be indicative of an abscess, which is a collection of pus that forms due to infection.
Another potential cause is a fungal infection, such as candidiasis, which can also lead to redness and irritation in the groin area. Fungal infections often thrive in warm, moist environments, making the scrotum a common site for such infections. Symptoms may include redness, swelling, and sometimes a white discharge, which could be mistaken for pus.

Eczema or dermatitis could also be a consideration, especially if you have a history of skin conditions. However, eczema typically presents with itching, which you mentioned is not present in your case.
Additionally, sexually transmitted infections (STIs) such as herpes or gonorrhea could cause similar symptoms, particularly if there are lesions or sores present. These infections often require specific treatments and should be evaluated by a healthcare professional.

Given the variety of potential causes, it is crucial to seek medical attention for an accurate diagnosis. A healthcare provider will likely perform a physical examination and may take a sample of any discharge for laboratory analysis. This will help determine the exact cause of your symptoms and guide appropriate treatment.

In the meantime, here are some general recommendations to manage discomfort:
1. Keep the Area Clean and Dry: Gently wash the area with mild soap and water, and ensure it is thoroughly dried afterward. Avoid using harsh soaps or products that may irritate the skin further.

2. Avoid Irritants: Steer clear of tight clothing and synthetic fabrics that may trap moisture and heat. Opt for loose-fitting, breathable cotton underwear.

3. Cold Compress: Applying a cold compress to the affected area may help reduce swelling and provide temporary relief from discomfort.

4. Over-the-Counter Pain Relief: If you experience pain, over-the-counter pain relievers like ibuprofen or acetaminophen may help alleviate discomfort.

5. Avoid Scratching: Although the area may feel uncomfortable, try to avoid scratching, as this can worsen irritation and potentially lead to further infection.

In conclusion, while there are several possible explanations for the symptoms you are experiencing, it is essential to consult a healthcare professional for a thorough evaluation and appropriate treatment. Early intervention can help prevent complications and ensure a swift recovery.
