When do concussion symptoms show up?
Two nights ago I hit the back of my head with force on a wooden floor (wearing a helmet). I immediately had some ringing/rushing in my ears but that subsided within minutes and I otherwise felt generally fine. There might have been a bit of foggy/loopy-ness, but I wasn’t completely sure if I was making that up. Yesterday I was ok too, I didn’t have to do anything cognitively or physically demanding but did some socialising. I did at times feel like I had a bit of pressure in my head, but nothing completely out of the ordinary that couldn’t have been explained by not drinking enough water or spending time in a room full of people.
At about midday today however I felt insanely tired and ended up napping for 2 hours. I am now getting like pangs of sharpish pain in the top and back of the head. this has gotten worse after coming back from grocery shopping. Is this kind of delayed onset consistent with a concussion?
