For the guys: How long would testicles hurt?
I'm a woman and I need to write a scene where a number of men does the Loki run (tying a slab of firewood to their balls and racing to the finish line).
I do not, obviously, have any experience of testicular trauma to draw wisdom from here. I'm not going to write this in any major detail but I need to know roughly how long this would hurt afterwards, assuming no serious injury. Hours? Days? How bad would the pain be the day, or days, after? How would this reasonably affect a person?
