where do you get a diagnosis of concussion? my partner fell down a flight of stairs, cracked his facial sinus bone, and required 18 stitches in his forehead, and still didn't get a diagnosis on his charts of concussion? We now figure this has been min. his 8th - and yet nothing in medical records history to show for it. Apparently its not unique, and very frustrating, you can have multiple hits to the head, and have cumulative damages, to the point where suddenly you have new behaviours, cognitive losses, pain, depression, anxiety, all of the above, and not have known anything about it. Be VERY careful, it seems like a bad joke, but putting on a helmet for everyday life, is now seemingly a good concept. you are not alone, but medically you might not get the help you need. listen to your own body, stay in the dark if you need to, sleep, repair the damages yourself. Good luck.
