I recently had a mole removed from the area above the upper lip. That was about 3 weeks ago. Excision with stitches. the stitches were removed 2 weeks ago. Everything was fine until about 4 days ago... there has been some protrusion on the wound along with a tingling sensation, some itch and redness.. today i noticed that a pus might be emerging.. there is hair growth on the wound site and i have tough stubbles around the area. Could there be a keloid scar forming on the area? the doctor told me that there would only be a line scar..
