itchy feet

Hi I don’t think that I have atheletes foot.
Because I don’t itch in between my toes and I don’t have bad toenails.
But I have small red bumps in the arch of my foot. and occasionally (like right now) The heel and arch of my foot itch terribly.
I can’t help but itch and now my foot is swallon.
But the small red bumps don’t seem to be the problem because they are always there and they don’t really itch.
I’m thinking maybe hives??? because some places on my arms and back itch and they swell up when I itch I don’t know…. any suggestions?? thanks Bridgette
