Bottom of the foot looks better.
I'd let the foot dry/keep unwrapped for a couple of days, see how it goes.
The odd colored skin, I would assume is from being wet while bandaged.
I'd just keep up with soaking for a few more days to see if that helps with the swelling.
I agree, even in the photos the scabs/roughness doesn't look like it would really come to a head.
Baytril might be the best choice to help with infection.
Yes, you would push like a Zit, but I think it would be a good idea to use the Clear (Decolorized) Iodine and see if that helps. I've not used it yet but have seen quite a few satisfied with the treatment results.
