Itchy feet burning sensation?

Usually at night my feet will tend to itch like crazy, feeling like they're on fire. There's no rash and it seems to otch most on ball of feet along with sole and between toes. My right foot's heel also seemed to be more elevated than my left and it hurt to walk ob as if i pinched a nerve. Its hard to sleep at night with the itch and burn, and im uncertain as to what this might be? my hands woyld also itch but not as bad as my feet. I also have a skin rash that comes and goes. This has been happening for 3 days, going on 4 as of right now. Thanks for your time, hope this all goes away soon!!:(
