I have a Hole where 2 incisions meet that has not healed 5 weeks post TT surgery. I went to doc. she removed a stitch and put a clean Q tip with peroxide in the hole, cut out some white substance she called dead skin, she placed a gauze inside, approx 1/4" deep, covered and said to repeat 2 times a day for 2 weeks. But when i do it seems to enlarge opening and reforms the white rubbery stuff she called dead skin. Normal? Common? would a butterfly stitch be better
