Oh you little worrywart! *Not saying I'm not, but how'd you manage to come up with the worst possible conclusion?* Now don't be silly and worry like that! Hopefully you'll be perfectly fine. I know this girl who had bone cancer in her knee (she's like 24 years old or so and the pain was so severe she couldn't stand or walk at all when it happened). Thank God she's been successfully treated and is now perfectly fine, but what I'm trying to say is, if it was that, the pain would probably be much much more severe. Go to the doctor and get it checked, but don't get to such upseting conclusions beforehand! Good luck!
