I was stepping out of the truck yesterday (it was icy) and my feet came out from under me. I bounced my head off of the cement and must have hit a little more on the left side since it is worse than the right. I had a bump on the back of my head, which is now pretty much gone. It got worse as the day went on and I was having some problems breathing which have calmed down some. Only deep breaths bother. My butt, back, neck , elbow , knee on the left side are bothered the most. It feels like I did 1000 ab crunches on my lower stomach. Not really sure if I can just take it easy to see if I start feeling better or what?
