I broke the radial head (funny bone) in my left arm in a bike accident. Believe me when I tell you that breaking your funny bone is not as funny as it sounds like it would be! I did no fall at a stop though- I flipped endo over the bars and landed on my arm because I was trying to shield my head for the pavement. I knew in about half a second after the crash that I'd broken my arm but instead of going to the Dr. I made my friends (we lived in a college dorm at the time) drive me to Wal-Mart to buy a sling for it. After 3 days it was hurting so bad I couldn't sleep and there wasn't enough alcohol on campus to numb the pain so I did finally go to the doctor. I had to keep the arm in a sling and no lifting anyhting heavier than a can of soda for a few weeks. It feels much better now [several years later] but I still can't straighten my left arm completely and I can feel where the fracture was when the weather changes (especally in the winter time).

Good luck and heal fast,
