It depends how hard the impact was. I know of incidents where the concussive person sustained permanent injury. I also know of people who were fine after two or three days. They can last months. They're really personalized, you can't ask someone else, unless that person is your doctor or examiner. I honestly have no idea, and I don't have the permit or the expirience to tell you. Just Hurry up and come back! I MISS U!!!!
You should really go the doctor and do not go to school or play any sports.It could end your chances at ever playing again.Trust me I have had one and I tried to play it through.And I still and probaly never will fully recover.Hope I Helped!
Again, depends on how hard the contact was. I know somebody named Osia who ended up missing six months of school and was held back a grade because of a concussion, but she was playing ice hockey without a helmet.
