Thanks for all the messages of support / abuse after I recieved after revealing to the world that my right ball was rather sore.
Apparently I have pulled a muscle in my groin and the pain I'm feeling in my ball is in fact 'referred pain'. So, no amputation is required.
I thought you could all mop your collective brow for me. Oh and yeah, thanks to DrDrill who encouraged me to get it checked - better safe than sorry guys...
