I fell about 2 weeks ago and have noticed the scab on my knee to be a green-yellow color with slight redness around the area. I'm also having some pain feels like bone pain when I bend my knee. Don't want to waste a trip to the dr if I'm just being a crazy hypochondriac. I've attached a pic - just copy and paste the link in your browser. any advice is appreciated
