Over a month ago, I cut quite badly on my arm. 3 cuts still look particularly bad, basically on each there is a huge flap of bright red slimy, what looks like fatty tissue hanging out and it is wet to the touch meaning when I bandage it it still bleeds through. I don’t know what the flaps are or if this is a problem? Because I’ve never cut that deep before but it really doesn’t look good. What is wrong with it? And what do I do?
