One day i thought I felt a small lump on the right side of my penis. I didnt want to make much of it so I forgot about it. A few days later I woke up and found the area was now bruised! I started to get really worried and so used some arnica oil which got rid of the bruising however now i think the lump may have got slightly bigger! I've felt pain at the top of my penis once or twice as well. The lump has appeared on a vein and I put the bruising and swelling down to a possible burst in the vein that has now healed but has left behind blood.... I really dont know what to do! Please help me if you can. I would be so grateful.
