I had a small yellow patch apear, i paniked thinking it was an infection starting. It was a few stitches that had pushed out. The nurse pulled them out for me but since then i have pulled 4 or 5 out myself when they have started poking out. Have a feel with clean hands obviously an if you feel anything sharp/prickly will probably be a few stitches if not you might be best getting it looked at just incase it is an infection. Xx
