Well after seeing the "chunks" they were removing from the bumble foot pics I was researching, the clear puss/gel that was in the middle of this foot had some "hardened" spots around the edges. That's So that's why I was thinking maybe it was early stages? If it WAS frostbite and I did what I did, will it still be ok?? Is it a good thing or bad thing that I messed with it if it was frostbite?
Neosporin it and vet wrap. Soak it some each day. Try to keep poo and shavings out. I see bag balm talked alot on here but have no experiance with it. With my blister i put a little hole in and squeezed it out so she still had outter skin on. I was able to take vet wrap off in like 5 days. You may want to let it fan or air dry after soaking try and let a scab or outer layer of skin to start forming some.
With how it looks i would think of it as your skin missing a few layers just enough to dot bleed and make white blood cells show up.
