I got when I fell down while boarding in the skatepark and it left me with this scab on my elbow, I placed a bandaid over it for some time but took it off the following day to let it get some fresh air. After a week and a half it was hardened by blood and bits of yellow, I peeled off the hardened blood and this thick yellow liquid seeped out, but the wound is still fleshy, how do I heal this thing?
