My son has only one testicle (the other was undesended and had to be removed when he was 6, he is now 11). This morning he woke with acute pain in his testicle. I took him to the nearby emergency room (not the children's hospital in our city) and they performed an ultra sound and ruled out testicular torsion. He was given morphine while there. We went home, but he is still in considerable pain. I am very concerned that he may have been misdiagnosed and torsion might still be an issue. Further, he was hit in the testicle 6 days ago (his friend accidently hit him with his hand pretty hard and there was extended pain and swelling). He was PAIN FREE for 5 days prior to pain begining this morning. Should I take him to the children's hospital? should I still be worried?
