I was in the emergency room last night and i have the flu. while i was there i told them my kidneys hurt so bad, of course they checked and kidneys were working but i was told one of my testicles had gone up inside me! its the weekend what do i do??

I wonder if this is a new finding because you have 2 testes in the scrotum all the time OR you have a non-descended or ectopic testis but you did not know. If your 2 testes are always present so you may have a condition called retractile testis which at times it moves up to the groin, not related to the "kidney pain". There is nothing urgent so you can make appointment with a urologist next week.
