My husband was recently in the ER for severe groin pain, they admitted him and kept him over night then it was decided it was not his appendix (which was enlarged) but referred him to a urologist for a cyst they found in his testicles and called it I belive the spelling is varicoli,,,,,is this something that requires biospy,,shoud we be concerned,,he has tried pain meds, antibotics hot and cold,,,it went away but now the pain is back?
