Possible damage to the testicles after active engage in oral sex, advice of urologist

Hello! I want to write about such a case. Girl with the sex sucked an egg at the man and pulled him up. A man jumped out from the intense pain. For a long time was sick. After 30 minutes the egg a little swollen. What it could be and how to treat? Whether there were such cases?

Response: "Hello! As soon as possible to address to the urologist and to perform ultrasound of the scrotum with Doppler. Maybe reactive inflammation of the scrotum, torsion of the testicle. Even if there were serious traumatic injuries, a survey to carry out desirable and in subsequent contact with the external genitals very carefully. I wish you health".
