do your feet just hurt but it does not hurt to just touch them or rub them but it hurts like heck to walk? I had this problem, still do, and it is my understanding that it gets into neurology that causes the pain. My rheumy recomended a dietary supplement, lipoic acid, buy over the counter, it does wonders for me and not adding another prescription. The prednisone never did anything for this pain for me. I believe there is a name for this however I could not begin to remember what it is. (you know you have brain fog when). Best of luck and Merry Christmas.
Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, who comforts us in all our tribulations, that we may be able to comfort those who are in any trouble, with the comfort wich we ourselves are comforted by God. 2 Corinthians 1:3
