Initially, I felt a sort of a lump at the base of my penis all around in the form of a circle, only at the base. That area has now become constricted and somewhat hard. There is no problems with urination or sex, but on pressing there is slight pain. On the other hand now it seems that the hardness area is spreading to the rest of the penis and it has almost covered the entire penis except the head area. As I said, there is considerable constriction at the base of the penis where the problem started. Kindly help.
