You need to realize that the next concussion will probably be worse. I have suffered several and I can tell you that I will never put myself in a position where I will risk another concussion. Its just not worth it to me. Every concussion I have had was worse than the previous. I am still feeling the effects of one I got in November. It sounds like your daughter had it pretty bad. She might play and never get another one, but is it worth the risk of permanent brain damage if she suffered another major concussion? Do your research and know the risks. I would say find another hobby, but thats just my opinion. I don't think its worth the risk.
