A ruptured testicle is certainly a possibility - honest! Bruising and swelling of the groin area is also a possibility. Treatment/transport in my area might consist of: placing the patient in a position of comfort, placing a cold pack on the affected area, inspecting the injured area only if severe swelling is suspected (usually we ask the patient to take a look first - it's quite embarassing for them!) Our paramedic's may consider starting an IV of normal saline depending upon the severity of the injury. More likely, they may just establish a saline lock.
