I have a bump (the sice of a pea) or smaller, between my anus and scrotum. It comes and goes over the last 7-9 years. It's starting to appear more often and stay longer. This last time a little pain. On the right side of very lower scrotum. Seems not so round but more oval in shape. I'm 46, ok shape, work out, no other conditions.
