Penile irritation with persistent moisture, itching, and small blister-like bumps over 4 days could be due to a few things â fungal infection (Candida balanitis) is common and causes exactly this picture of moisture, itching, and skin changes. However, blister-type lesions also need to be evaluated in person to rule out other causes, as treatment differs depending on the exact diagnosis. This needs a proper physical examination by a dermatologist or urologist rather than self-treatment.
Next Steps
See a dermatologist or urologist in person as soon as possible for an examination. In the meantime, keep the area clean and completely dry, wear loose cotton underwear, and avoid any creams without medical advice. Do not delay the consultation given the blistering. Please consult me directly on Practo for a detailed evaluation.
