From what I was seeing in the photos, there was something like bacteria at work, consuming tissue, blistering, and leaving runny sores. The castor oil and soaks were not halting this process. There should have been noticeable overall improvement if it were leg mites.
Sometimes it requires more than one brain working in concert to get the full effect of a single brain. Ummm, at our age, especially.
