On last thursday i took a spill down some stairs and busted open my lip, there was minor bleeding and today after the pink scabs are gone the large black scab at the center of the cut remains but is cracked down the middle. should i see if the cracked pieces come off or leave it alone? I also have 3 giant purple bruises from the fall that seem to only be growing, should i get them checked out even though my bones feel fine. There are two on my knee, the biggest (tangerine size) is starting to throb, and there is one on my backside that showed up on monday and is continuing to grow.
