I had a Pilonidal Cysectomy (I m not sure how you spell it) on the 20th of December. On the 31st I went in to get the stitches removed, but there was still a hole at the bottom of the suture that hadn t healed. There s discharge , and my doctor told me to pack it with gauze , to keep it dry. The past couple of days, when I took out the gauze, there was slightly yellow discharge on it along with some pink discharge and it smelled of fish or something. When I took the gauze out about 20 minutes ago, there was less pinkish discharge, but it smelled almost like clorox bleach... Is this a sign of infection, or of healing?
