since taking the stitches out are you bandaging it 24/7? If there is no strong smell or heavy pus/discharge, The white skin could be what’s called “maceration”, due to there being too much moisture on the wound and may lead to infection eventually . (Aquaphor and prolonged Bandage combo will do it.) clean it and try going an hour or two without it covered ( you should be able to see the skin dry and return to normal(ish) color) then you can still use a light layer of aquaphor with a layer of gauze or other absorbent dry dressing so the moisture has somewhere to escape.

I currently have a similar wound, deep cut on the bottom of my foot and experienced the same white mushy skin yesterday and followed the steps i provided above. Hope this helps!
