Hey, last tuesday I was playing baseball and I slid late into the bag and really banged up my knee. Ever since then I've been trying to cover it up with band aids (I've washed it with iodine about 10 times now) but the cut won't form a scab, I move my knee around too much for one to form. It's now been a week and it's still open. I had a big bandage on it yesterday but I bumped my knee and it broke whatever scab was begining to form and the cut started to bond to the bandage. Sorry if this is graphic but I have no idea how to treat this and make it go away. Any ideas? I might take a pic sometime later if anyone wants to see.
