Hello and welcome to Neuro talk. You for sure will find alot of good people here to talk to. Sounds like you did bang your head pretty good. I understand about being a teacher and having to be 100%. I hope some others will chime in and talk about concussions. Most mild ones, from what people have related to me here, go away on their own in not too long. If this carrys on too long, you maybe should see a neurologist for evaluation. I hope you get better soon, with no side effects getting in the way of you being the best teacher you can be. We all need you and so do our children. ginnie
