Bob-O, hope you ride it out okay. I might even suggest going ahead and getting a CT scan, especially if you can work it through insurance where you don't get charged an arm and a leg. Just something to consider. Small price to pay to have a bit of comfort that all is good in the noggin'.
I had a pretty nasty concussion when I tried to learn how to snowboard on the icy slopes at Big Bear. It didn't help that I passed out in the parking lot post crash and hit my head AGAIN on the asphalt. When I started throwing up, they hauled me off to the ER. All was okay, but it was finals week, and I had to take three of my finals with a messed up head. That wasn't fun.
I had one fall a few weeks ago with my old worn down vibram boots I was telling you about, and I * near broke my wrist. Falling backwards and putting your arms back to brace the fall is an easy way to snap a bone, especially when you're as big as I am. Told myself to stop being so stingy and go get new boots. The Patagonia's worked awesome their first time out and it sure felt good to stand up right again on the water. And that was without the studs. It's their own material, I believe, so not exactly Vibram.
If anyone is a size 10 (sized to fit booties and thick socks, so a true size 11-11.5), they have them on sale:
