From one extremity to the other!
On coming back from my treks while on high doses of prednisolone I would notice that my feet were bright red and slightly sore. I didn't twig that this thinning of the skin with the pred would affect the feet but it did.
On the plus side I have not had any hard skin on my heels, my feet are so soft at the moment.
Not that I would recommend taking pred for hard and cracked heels but it works, well it does for me!!
Anyone else had similar?
