i ate it when i was surfing and i did a frontflip then the fin of my board sliced my head open. now theres a big flap of skin dangling from my head. i went to the doctor and got it glued (i didnt want stitches). then i put my headphones on to play drums and it ripped the flap up. Should i go back to the doctor and get stitches so it stays in or should i let it heal by itself? some kids said that its too late to go back and get stitches since the cut is all crusty and stuff. is this true? help i dont wanna have like an infected head.
