Patient's question:
The past two years, I had this illness once, and it took six months to recover. Now I've gotten it again. The head area is always red, and it's almost a year now with no improvement. At first, it was very severe, with small bumps on top. Although they're gone now, it's still red, and there's a faint layer remaining, accompanied by a burning sensation and urgency to urinate when drinking alcohol, as well as swelling.Doctor's answer:
Balanitis refers to the inflammation of the glans penis. It is caused by various pathogens, local irritation, and other factors. Balanoposthitis refers to the inflammation of the inner foreskin and the glans penis. A normal foreskin cavity secretes a lipid substance. When the foreskin is too long or there is phimosis, this substance can accumulate as smegma, irritating the foreskin and glans penis, leading to balanoposthitis. Drug allergy-induced balanitis is a delayed-type hypersensitivity reaction and is quite common clinically. It typically manifests 24 to 72 hours after medication.
