Yes, I'd definitely go to the ER ... The sooner you have this checked out the better!

Not to scare you, but our director was walking through the shop last September and hit his head on an open hatch of a bus that was being worked on in the shop. It ruptured a blood vessel in his brain and three months later so much blood had seeped into an area of the brain it was as if he was having a stroke! Fortunately they were able to fix it, but they had to do a major surgical procedure to accomplish that! There was no permanent damage and his recovery was spectacular! However, had he had it checked out when it happened it could have remedied by less invasive means.

Any head injury, no matter how mild it may seem, needs to be checked out as soon as possible ...

Therefore, hie thee to your local ER today and without further delay!

Sincerely,
Pfrog!
