Patient's question:
The head of my penis has developed red spots. I haven't had any recent unprotected sex. The only thing is that I washed my socks and underwear together a couple of days ago. I have athlete's foot.Doctor's answer:
You are describing balanitis, which can be caused by phimosis, excessive foreskin, groin eczema, or sexually transmitted diseases. It is recommended to receive intravenous antibiotics, sit in a bath with potassium permanganate solution, actively treat the primary disease, avoid spicy foods, and prevent cross-infection.
