Can you tell if it's just skin or into muscle? Because unless it's pretty deep it would be fine most likely, my midwives I've had said they avoid stitching as long as things aren't very deep and still line up fine, that stitches just add several more wounds to heal where the needle goes in. Does everything seem to lay right so it can heal just as it is if you stay mostly still a while, or does it seem to need to be fixed in place to heal properly? New-skin liquid bandage is a possible home treatment if it's shallow but needs a little help holding together. Do stay in bed more to let things heal, moving around won't help it one bit.
