question: I have shingles... Could that be what is causing my feet to hurt when I stand and walk sometimes? I have had corns on the pads of my feet, but not any of the shingles rash. And it is the pads and heels that hurt really bad when I stand up and sometimes when I m sitting or sleeping! And I have other parts that hurt sometimes for no apparent reason! Like under my left arm and breast. But none of the pain is all the time... But several times a day.
