I got a mild concussion 2 days ago and most of the symptoms have gone away besides the occasional nausea, ive been able to play video games without getting a headache if that helps. i was wondering if masturbating would be dangerous?

Do something else: If trying to stay on the safe side, avoid over-using the brain after a concussion. That means don't study too vigorously, don't take an SAT test nor use brain power for video games, and don't spend time worrying about masturbation. Over-worrying is over-using the brain, so over-worrying is to be avoided. Also, if trying to be safe, just think of masturbation as having the intensity of a sport.
