What should I do?
I was doing athletics yesterday, and I was trying to have a technical urdles right, but I hit a hurlde scraped knee and the other hard on the ground. this was on a track, so it was difficult to sand and dirt. I have a big mess on my knee, but instead go to first aid which I wash in the bathroom. Last night it started hurting pretty bad, so my mother washed it for me, and dirty this morning, so I washed again, but it is still very sensitive to movement, and difficult to walk, so lame. should this be happening? What I can do?
It's probably just sore from being badly bruised and scraped. If it is swollen put some ice in a couple of times a day, 20 minutes at a time. If it is red and oozing however, go to a doctor because it could be infected and may require antibiotics.
