If any one can offer advice for treating the foot at the above location it will be greatly appreciated.
She has been through 2 rounds of bacterial and fungus therapy 2 different foot pad treatments human anti fungus, coppertox and still as soon as ran 1 time after getting well it comes right back.
All advice appreciated

Let her stand with foot in pan of kerosene covering the whole foot and occasionally move her around so it changes foots stance. Do this twice a day for 5 minutes or so each time. When it looks like its well, stand foot in the old diesel oil that is for farm equipment only as it has lots of sulfur in it and will finish the healing and harden the foot and pad.
Good luck!
