I am the caregiver for my MIL who has Alzheimer's. I have now noticed her feet are stinky when I am putting on her compression socks and trimming her toe nails. She hates showers but I get her in there 2-3 times a week. She is diabetic, overweight a bit and has bad leg circulation. Maybe this is a fungus? Should I soak her feet in a solution of vinegar or Epsom salts or baking soda? Take her to a dermatologist or a podiatrist?
