I randomly came across this thread, this morning, and low and behold the same thing happened to me last week, while snowboarding in Colorado
Tanner Jr. and I went over to the side of the mountain (Snowmass) that we hadn't ridden yet, and on the first run, realized we could have made a better choice. It was just a pretty narrow run that had quite a few patches of ice, that were hidden by the inch or snow of fresh snow.
We were taking it super easy and mostly just doing the 'pendulum' to get down this pretty terrible run. Alas, it seemed to get a little bit better so I decided to try and ride the 'regular' way, so I pointed my nose down and went for it.........
First heel side to toe side carve was fine, but on the next transition to heel side, I hit a hidden patch of ice, lost my edge and banana-peeled out, landing on the back of my head.
Thank God I had a helmet on.
Everything went dark for a split second, and instead of stars I saw two squares (one yellow, one blue)!
It happened so freaking fast that I couldn't believe it and sat right back up, mad as hell and cursing
I think the adrenaline was what kept me going, and the run shortly intersected with a much better one, so we got down to the base with ease, the rest of the way.
We ended up doing two more runs and Tanner Jr. actually told me those were my best two runs of the trip!
Then, it was early afternoon and we hadn't eaten lunch yet, so I said lets take a break and get some food and water.
We parked in the garage at the base of the hill, so we could have easy access to the car and our stuff, so we put our boards in a rack and started walking to the car.
About halfway there (and it was a pretty short distance) I started to feel a little weird. Got in the elevator, to go one floor down and really started to feel 'fuzzy'. Got off the elevator, walked about 20 yards in the garage and had to stop because I thought I was going to puke (I didn't).
We had a hatchback, so I popped it and we sat in the back having water and snacks, and I felt much better after about 20 minutes. Decided I would try a few more runs and then probably call it a day.
I made it about halfway back to the elevator and had to stop again because I thought I was going to puke (again, I didn't).
We were staying with family, who live locally, and I ended up having to call them to come get us, because I knew there was no way I should be driving.
Family member knows the on-site doctor at Snowmass, so after they arrived we went over there, but that Doctor had just left for the day. Nurse came out, asked me a bunch of questions (by that point I was super fuzzy), checked my eyes, etc. and said 'Definitely a mild concussion' then asked if the helmet was mine or a rental. When I said rental, she said 'When you return it, tell them to take it out of the rental fleet'.
Went directly home, and only had some light conversation (no phone, no computer, etc) for a few hours (family said I was occasionally repeating myself), then when it got dark, basically sequestered myself in a bedroom for a few more hours. Ate some bland food and went to bed.
The next morning I did feel better, but holy hell did my neck hurt (like whiplash). Went to a family friend who's a chiropractor and she took care of that, along with a few other things.
We hooked Tanner Jr. up with some other family friends who were riding that day, so he could keep the dream going, and I literally sat at the fire pit at the base of the mountain all day, just chilling (again, no phone, no computer). Felt even better by the end of that day.
Next day (our last day of the trip) we just cruised around so Tanner Jr. could hit a few skateparks and we could take in some sites, etc.. Super low key, and I wasn't driving, but did start to look at my phone a little bit and again, felt better.
Day after that (last Saturday), we flew home and I was a little nervous about getting on the flight, but everything was great, and I felt fine.
Spent Sunday basically doing nothing, except hanging at home with the family, watching movies, etc.
Went to work on Monday morning, and dove right back into it. No problems all week, and didn't feel 'off' at all.
Purposely didn't surf or skate all this week, but am thinking about paddling out tomorrow on a longer board, to take it easy and see how it goes.
