I have a cluster not directly attached to right testical. About 10 days ago (after horse back riding) I noticed pain in my testical. I thought I had perhaps unknowingly hurt it while trotting the horse. The pain went away after a day or two. A few days later I noticed a cluster not directly attached to right testical. It is on the south side and seems to be like a bunch of enlarged veins. I am 55...in good health. What could this be? Should I get it checked or just watch it for a month or so?
