had stitches removed from my right upper arm, yesterday. Stitches were applied 1 week prior to yesterday. when I woke up this morning , I noticed blood on my shirt. Noticed that the wound had reopened, from a 3 stitch procedure. The wound has now opened to 3/16 wide X 3/8 long, which was about the length of the original opening. what should we do, to minimize the scarring?
