wow...have had the same problems with my feet since i fell in the shower in dec. think it is from rsd... my feet are either burning hot or ice ice cold and nothing warms them..can't put socks on for long..they make the pain and cramping worse...it changes from electrical shocking to the feeling of having a charlie-horse from my ankle to toes and the whole bottom of my feet..worse on the left side..(as everything else always is) keeps me up all night...or wakes me from my deep, deep sleep that nothing seems to wake me from... so many questions.....no answers..... i sometimes use a small massager on the bottoms..for a very short time.. just letting you know that you are not alone....could be fibro??? i have that too... moonstar
