The appearance of small, itchy bumps on the scrotum's hair follicles can be caused by a variety of reasons, including folliculitis and fungal infections. This condition is usually accompanied by local redness, swelling, pain, or burning sensations, and sometimes pustules or dandruff.

If symptoms occur in a damp or hot environment, or if personal hygiene is poor, it may indicate a fungal infection. Fungal infections are often more likely to occur in warm, humid environments, such as wearing tight clothing for extended periods or not changing into dry clothes promptly after exercise. Another possibility is a bacterial infection, such as Staphylococcus aureus, which is usually accompanied by redness, swelling, pain, and possibly purulent discharge.

If the itching is accompanied by severe pain, fever, widespread redness or swelling of the affected skin, or even affects walking or standing, it may indicate a more serious infection and requires immediate medical attention. Avoid self-medication, as inappropriate treatment may worsen symptoms or cause the infection to spread.

[Prevention Tips:]
1. Maintain personal hygiene, clean the scrotum area regularly, and use a mild, non-irritating cleanser.
2. Wear breathable cotton underwear and avoid wearing tight clothing for extended periods.
3. Change into dry clothes promptly after exercise to keep the affected skin dry.
4. Avoid sharing personal items such as towels and bed sheets with others to reduce the risk of cross-infection.
