Since I've been working alot of hours during the cook-offs last summer, my left foot seem to bother me as much as my right foot does, feeling horrible pains and swelling, but for the past few days, I'm experiences " electric shock " on the bottom of my left foot, and this symptoms seem to appear and disappear off and on lately, have anyone ever experiences this before? and what exactly does this cause? and do I have to see a regular doctor or a foot doctor, forgive me if this sounds like a stupid question but I 've never been to a foot doctor before....
