I bruised my bicep, my buttocks, and really hurt my finger. I went into go see Sean today because I was convinced I had broken my finger. It hurt to bend. After an x-ray and an examination he let me know that I only sprained my finger. I feel so foolish, especially because Brian warned me so many times not to do it. I guess I should feel lucky I didn't break anything! I will never buy one of those for my own home!
