If you work around sharp objects, or just everyday life, you’re liable to get cut by something sharp every now and then…
And at least in my case my feet seems to develop cracks at the heel, and it HURTS to walk.
And the annoying thing is, those sharp cuts or cracks in the skin won’t heal as long as they are open, and it’s hard for it to stay closed. Worse yet, if you use your hand to wash the dish, wash your hand after using the toilet (which you should, especially nowadays), having an open cut is bad for you.
So next time you get those sharp cuts or cracks where you can hold it closed with your fingers, get some thin superglue (the kind that flows into even the tiniest cracks), and while holding the cut or crack closed with your finger or whatever put a drop of superglue right into the cut. The cut is now glued shut and will not open up. And while the glue dissolves (takes a couple of days) the cut heals over and you won’t even notice it. Try it, it works.
They have medical version of these things if you don’t feel like using hardware store variety.
I have cracks in my foot and it really hurts to walk, and after gluing those cracks shut it doesn’t hurt anymore.
