A doctor will just look at it to see if it's healing, and not getting infected, or rotting away. The flesh will start to adhere to the stiches if you don't take them out soon enough. I would pull them on the sixth day. Make sure you clean it really well before you start messing around with it. Peroxide is what I would use to clean it. Do like was posted above. Snip, snip, snip, and ease them on out. Then put some neosporin on a gauze, wrap it up and tape it. Get one of those plastic "sore finger guards" and tape it on to keep from bumping it, or you will cuss and dance around in funny ways when you do. . .
