question: I fell off my skateboard about two weeks ago and have a few ugly scratches over various parts of my body. The one on my left knee is the one I am worried about. It is being quite bothersome compared to the other ones. At night when i sleep, the scab comes off and whatever fabric I am wearing, the fibers go in it. If i put a bandage on it, by the morning, it seems as though the scab had formed within the bandage, so pulling it off is quite painful. As of now, I was trying to see if it still hurts when it started oozing out this yellowish brown liquid. It seems to be kind of mucusy. What do I do?
