To make a long story short, at gymnastics on Thursday I was accidentally kicked in the head (really hard), and I started getting dizzy and a really bad headache. I went to the nurse's office at my school on Friday, told that I most likely had a concussion. My mom called the doctor's office, but they had already closed for the weekend. She was able to find out that you can have the symptoms for 7-10 days!!!! Anyway, I am still getting dizzy and headaches, but I have gymnastics tomorrow and a meet this coming weekend. I really need to practice, but I don't know what I can and cannot do. Have any of you had a concussion before? What precautions should I take? Thank you for all of your comments. Oh, if it helps I'm a L6.
