I used ointment and tablets for itching on buttocks (skin disease. It got cured. Last night in the sleep I got slight itching on my penis skin. I gently rubbed and later after few minutes when I went for washroom ,i noticed that the skin became swollen. What I did is, I removed my inner garment and short slept under the fan. After 2 hra it became normal. This is the second time. Last two days I missed to apply ointment for itching. Will be there any problem in regard with penis.
