Hello,I had my tt Aug. 21st. The incision opened about 2 months ago- bad, deep, ugly opening which tore more and more every day. It is healing very well and is closing up quickly now. I see my ps everyday so he can monitor it. This morning, he decided to put silver nitrate on it even though he said it was looking great. Why? What does this do for the incision? Thank you so much in advance.
