I had a mole excision on 4/12/17. The mole was removed from right side of nose.MY plastic surgeon did a vertical excision. On day 3 it appeared the wound was more open that closed but he assured me there were stitches placed under and on top of the skin so not to worry. The wound from the second day had a goopy yellow/ gray color and still does to this day. I keep moist with Vaseline , 3 X a day to prevent a scab. what should I be doing?
