Husband is almost completely sedentary and has put on a lot of weight over lock downs. His feet are a bit of a mess. They are kind of reddish, covered in small wounds all the time. He has had a bad fungal nail infection in all his nails for over a year and it's so painful he can't walk properly. He refuses to go to the doctor, says he's too embarrassed. I did the Google thing and it suggested these can be symptoms of diabetic foot, so now I'm very concerned. Do these symptoms ring a bell with anyone?
