I've had this happen to me for many years now but am just wondering if anyone else has it. Basically maybe once or twice a day my right (always that one) bollock rises up into the sac. I went to the doctors many years ago but of course it never did it whenever they examined it. I know nothing of it - I can't feel it and the only way I know is if I pull my pants down and it's gone high up. I then push it back down again. Sometimes if it's a bit tighter than usual I can feel a sort of a plonk feeling as it clicks back into position when I'm pushing it down. It doesn't hurt and it's done it for more than 10 years without any effects. Just annoying when it does it that's all. Anyone else had this?
