I agree with SmilinEyes. I am a teacher and taught through my first week with a concussion. Even after I took off a few days to "rest," I was still sending in lesson plans, checking work email, and finishing up semester grades. As a result of not being able to take off a few days at first, I have now been forced to take off five months (so far) and am uncertain if I will be able to return to work when school starts again in the fall.

Physical rest is important, but so is brain rest. Eliminate as many sensory inputs as you can until your symptoms subside.

Good luck!
