I would say that a helpful tip for having a concussion is audiobooks are your next best friend. I remember having to sit in a dark room not being able to look at a tv or a phone for a long time and audiobooks became my best friend. They entertained me for hours and hours and hours when I was just sitting in a dark room with no lights.
I grew up playing football, so football usually comes with lots of concussions, and so I dealt with that on multiple occasions. And the best advice I can give is not to ignore it, I guess. I guess that was kind of a culture, at least when I was growing up, I think it's kind of changing now, where if your head starts to hurt a little bit, it's natural, just let it happen. But obviously studies have shown that that's not a good thing to do. Don't ignore it if your head starts to hurt while you're playing football or any other sport. You should pay attention to that and seek medical attention and try to get that taken care of, because there can be long-term lasting effects that are very dangerous.
I think it's best just to rest and restrain from playing any kind of physical sport because it's not good to do that when you're in a concussion. I had a concussion from basketball and it was not good but continue to play and you don't want to do that.
