I’m with @Jimbob here. It’s hard to tell from the photo for sure, but is the skin arouns it red, warm to the touch, or developing whitehead pimples?
I sometimes get cracks on the bottom of my feet. I’ve found that if I get some kind of ointment and put it on the cracks it helps a LOT. I get most of that kind of ointment at the “Dollar Tree”. They have some great bargains on that kind of thing. A tube of ointment for your teeth that costs six dollars at Walmart costs $1 at the “Dollar Tree”. I bet it is the same way with foot ointment.
The soldiers in the trenches in World War I were having terrible problems with “trench feet”. They often lost their feet to this condition. Then they discovered that if they took their boots off every four hours and rubbed their feet with cooking oil it solved the problem.
Wow that looks painful! Think it’s time to see the doctor, you don’t want that to get infected. You only get two feet so ya gotta take care of them!
My heels crack and bleed too. I got a skin file at the drug store. I used a razor first and cut off as much of the callous skin on my heels. Then I used the skin file and filed it down as much as possible. Then I used lotion with aloe. It stung a little but getting rid of all the callous helped.
You need to work your calluses down regularly or they get so thick they crack. Get what is essentially a large emery board for feet from the dollar store or pharmacy. You file down the calluses once a week until your feet are soft again. I walk so much that I’m prone to thick calluses on my feet if I don’t constantly maintain them.
