The pain is as if my socks were curling up under my toes while I walk. This problem would come and go but as I aged (73) the problem seems more prevelent and longer lasting.
I've been having a similar problem. In my case I suspected it might be related to my diabetes, but my doctor doesn't seem to know what is causing it. I wish I could give you a better answer, but I can't seem to get an answer myself yet.
