I have had 3 surgeries to remove a pilonidal cyst and the last one, 2 years ago, used a different method to heal the area. It was a 3 point area where they took tissue from another section of my butt and filled the gap to speed the process. The wound still has not healed completely. It does not hurt, but there is an opening that occasionally bleeds and won't close. Should I see a specialist, or a plastic surgeon?
