Replying to Yo doctor NS!

So basicely I ate it on some stairs hitting urban, and had to get two stitches on my upper thigh, rather than making a trip to the hospital to pull out just two stitches, I figured I could just get em out myself. I cut the knot on one of them, and accidentally snipped both ends of the knot, and the stitch dissappeared under the skin. I went to the doctor and he just said to leave it and let it work its way out, or it would heal over and stay in there forever, or it would get infected and he would then be able to find it and pull it out.

Anyone else have this problem before?
