If you do fall on your side make sure to keep your elbows in. I chipped an elbow doin that once and didn't realize that the pain I was feeling for a week could have been something serious. Went to the doctor and got an X-ray. Defiantly chipped then had to get an MRI or whatever because they thought I chipped a growth plate ( I was 13 at the time). If I had, my arm would have grown crooked. Thank god I didn't.
