At first it was really red now it's black blister like bubbles like it wants to peel
Thank you for your questions and photos. It appears that you might be having some poor blood flow to the skin on the right side of the vertical incision which can cause blistering and weeping. I would visit with your surgeon to have them evaluate the area. Sometimes the skin that is farthest away from blood supply can have healing issues. Good luck.
I'm sorry that you are having trouble with healing. Blistering is not normal after a tummy tuck. I suggest you follow up with your surgeon to help treat the problem areas you have identified. Best wishes.
