We have been dealing with bumblefoot for awhile/ 2 times daily epsen salt soaks, decolorized iodine, and triple antibiotic cream. I then Bandage. We did do 2 surgery’s, to remove dead skin and try to get the kernel. I’m struggling to identify, what is not infected skin. How does this look? Should I be removing the grayish material forming? Or is this what the healing process looks like. Any help would be awesomen!!
