Just last week. My heel felt like the skin was getting ready to split, but I take good care of my feet and they're not that caloused. I worked on it with my Amope foot thingy and rubbed some good foot cream in and it helped. It could also be neuropathy, in which case you need to talk to your Dr.
Possibility of a food fungus diabetics are prone to this. You might want to try a foot soak nightly for 15 minutes in apple cider vinegar. How do your toe nails look?
I would get this checked out by your doctor
Thanks Suecsdy , it could be neuropathy, I I dont have callouses, and I do take care of my feet, there is also no physical signs like redness or rash or anything, my doctor prescribed a steroid dermatitis cream , just wanna try and see before I go for a follow up
