Even if it was true that he was experiencing period cramping (it's bull, readers), a man has experienced a menstrual cramp after years as a male and thought he needed to go to the hospital because his appendix was ruptured. The same thing that happens to women every month and we are meant to take ibuprofen, drink a herbal tea and go to school/work and stop making a fuss (not to even mention the actual period part).
This is an amazing insight into how Male these individuals truly are, they can't even imagine what we go through and also know that they won't be looked at like a silly girl for bothering the doctor. He's a bloke, they'll run tests and reassure him, they always will.
