What should I do if I have red pimples on my penis?

Red pimples on the penis may be caused by allergies, bacterial infections, viral infections, etc.

Generally due to systemic or local allergies caused by the environment, underwear material, etc., red acne will appear on the penis, and symptoms of pruritus often appear. To remove allergens and keep the penis clean and dry, you can apply ointments such as dexamethasone ointment, or take anti-allergic drugs such as cetirizine ；

Diseases such as folliculitis and sebaceous cyst are more serious. If folliculitis is serious, it will develop into chronic disease. Excessive penis foreskin may be due to the excessive growth of the penis foreskin, which causes a large number of pathogenic microorganisms to multiply. Unclean sexual life and poor personal hygiene can also lead to infectious inflammation of the penis. It needs to be treated with some antibacterial drugs under the guidance of a doctor. If the sebaceous cyst is serious, surgical incision and drainage can be used. ；

Common sexually transmitted diseases such as genital warts, genital herpes, herpes zoster and other viral infections will cause red acne on the penis, as well as varying degrees of swelling and pain, abnormal discharge, skin damage and other symptoms. Both men and women have sexually transmitted diseases. Genital warts are commonly treated with imiquimod. In severe cases, surgical excision, laser, freezing and other methods can be used to remove the lesions.
