What disease is there a red rash and a little itching on the glans penis?

Erythema glans is more common in male prepuce balanitis. Its etiology can be seen in too long prepuce, phimosis, masturbation, traumatic infection, etc., which leads to exfoliation of keratinized epithelium and secretion of glands, which forms good breeding conditions for other bacteria and causes inflammation. Its clinical manifestations are mostly local itching, redness, erosion, and even ulceration, with secretion and peculiar smell. In severe cases, it can have fever and chills. It is recommended to go to the hospital for post-examination treatment. Pay attention to the hygiene of the external genitalia, have long prepuce or phimosis and have early surgical treatment, avoid unclean sex life, dress loosely, and avoid spicy stimulation in diet, etc. I wish you good health!
