I have a smalllump on my testicle, feels like a small bit of grit sometimes it's easy found but other times i have to search for it before i find it, I have been to the doctor and he says it is a syst, I would love to believe him but I don't even think he felt what i was talking about, most days i have a dull pain depending on which way i sit down but it's sure to appear at some stage, anyone got any ideas on this?
