My 9 yr old grand-son's testicle is swollen as large as a baseball, on one side the other is normal; when I asked him how long it has been like this he couldn't remember,but he did say that it goes back down after a period of time.I have a appt. with his pediatrician for tomorrow, but, I need to know if I should take him to the E.R. now not wait till tomorrow; he's not in any pain or discomfort or says he's not.
