Take care of those stitches and don't stress them. I got 36 a few years back when a utility blade met my thigh. All the way to the bone, 18 stitches inside, and 18 on the outside. It took a while for the muscles to grow back together and have some strength. Mine was vertical, and I assume yours is a horizontal cut. That's hard not to stress, but do your best not to hurt it more.
