My daughter was on the treadmill (walking machine) yesterday. She was running on a high speed and couldn't stop the machine and fell. She got her legs caught under the treadmill and it burned her knees. I just learned to never let your kid/kids walk or run on the treadmill without supervision. Here's a pix of my daughters knee..
OUCH!!!
OUCH!!!

for me and tell her I hope her boo boo feels better soon

Anyway.. I checked on my daughter's knees and the swell has gone down and the infection looked like is gone now. So, I asked her how she felt she said she was better than yesterday. I decided not to take her to the dr. I'm just going to keep an eye on it just in case she didn't have problems inside of her knees. Thanks everyone for the concern! 

That's quite a scrape there. *cringes* at photo. Poor girl!! I'm glad she's ok though. What was she doing on treadmill anyway?
