What can I do about Mother-in-Law's stinky feet?

Medicare covers for a podiatrist to cut toenails every 10/12 weeks. This is not something you should really do especially with a diabetic. Nurses in care facilities are not allowed to cut toenails because of infections that can happen. If you can't get MIL to one, see if one does house calls.

Don't want to be alarmist but with diabetes and poor circulation this could be quite serious. If she were mine I'd want her checked out by a doctor to make sure there isn't a nasty infection going on. Nothing to see, is there?

Checking with a podiatrist is my recommendation, once you know what you are dealing with you can go from there.

I don’t recommend using a hair dryer to dry between the toes AT ALL. Diabetics have neuropathy and may not feel a burn if you use a hairdryer. You can do more harm than good in an instant. A simple cotton towel will do.

If you can’t get MIL out of the house, contact a company like Visiting Physicians, a company of medical professionals who makes house calls. They have a network of specialists, including podiatrists, that they can send out. It’s covered by Medicare.

People with diabetes who cannot learn how to care for their feet due to dementia, etc., should see a podiatrist. Make an appointment with a podiatrist and learn how to care for her feet between visits. People with diabetes have a harder time healing and certain solutions such as Epsom salts, etc. may make their condition worse.

My mom also gets sweaty, stinky feet. My recommendation:
Twice weekly, soak her feet in apple cider vinegar, for 15 minutes. Rinse well. Dry very well. Apply anti-fungal powder daily, between toes.
Medicare does cover Nail Care by Podiatrist for Diabetics, every 60 days.

Just get some lotrimin foot cream and put it on as directed. It will kill the bacteria that is causing the problem works great. You may need to get her new slippers or shoes though once it gets in the shoes its hard to get out

Our son was born with stinky feet. I washed them twice a day with antibacterial soap, and that helped a little. Then, a nursing friend suggested that I mix warm water and white vinegar (equal amounts) and apply to his feet, let air dry, and then rinse with warm water. I did and his problem disappeared. Had to reapply when our son was a teenager. Tried this on my husband (his feet smelled so bad, the family dog would roll on his feet when he took off his shoes), and his feet have never smelled bad since. (The nurse said that fungus gets around the toenails and smells bad.) I don't know the science, but this really worked for our family. Amazing. Hope this will help.

The doctor says she has athletes foot . Over the counter treatments should work. Also to freeze her shoes for 4 days. She has been wearing the compression socks for years. Thank you all for the many good suggestions and advice.
