What causes white crust on the opening of penis and pain during urination?
human
Is it normal to have a white crust or buildup around the opening of my penis.  I was on some antibiotics for a sinus infection and have recently noticed a white crust on the opening of my penis, usually in the morning after sleep.  THis morning I experienced a sharp pain when urinating but everything has been fine since then.

Hello, This may be simple "Smegma" (secretion that accumulates there) which needs cleaning and maintaining hygiene. However, as you have pain, it may be because of infection. In that case, also maintaining hygiene is important. Take plenty of water. Check urine for culture to find out whether there is infection. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Sujoy Dasgupta
