B: You'r making a good start but need fine-tuning a bit. First, as for footbaths, the ACV I would replace with unscented Bleach maybe once a week, and do one big spoon of Borax daily. As for ACV orally, you can buy ACV tablets at health food stores, so no more bad taste or irritation.
As for topical treatment replace the Oregano with Garlic Oil and do daily for a couple weeks then rotate to Pure Grain Alcohol (180 proof) and either Tea Tree or Eucalyptus Oil. The ratio of each you may determine at a tolerable level, maybe start w/ 50/50 in an small glass bottle and dab on with cotton swab for 2 wks then back to the Garlic.
When sleeping, keep that foot free of covers as to keep moisture down and fresh air around. A small fan on that foot would help. Speaking of air, be sure to keep your house filters clean or replaced and consider additional air purification as fungus cannot grow in a clean or well oxygenated environment.
