Feet and toes feel like elastic bands snapping?

hi, I can only say that when new patches of psoriasis form , the first feeling for a very long time is of "burning". later on it starts itching for a long time, and only after that you can actually see a patch of psoriasis/ the other thing I thought of as I read you r post is to check your blood sugar levels to make sure you do not have diabetes ( neuropathy) . teh third thing, is to check whether you have inflammation in your spine - i had and it cause burning and numbing in my feet and hands. when the inflammation cleared that sensation cleared too/
