Hi, i had a surgery and circumcision when I was 9 years old. i have always had  a tiny bump near the stitch as a result of the surgery under the upper skin of my penis shaft. For a couple of days, I am noticing the bump has swollen and white fluid discharge comes out at times from it. It is painful only when touched. It feels like an infection, please suggest. I am trying to avoid going to any hospital at this time, so thought to consult online before I do.
