Is it possible you have an ingrown toenail from the pressure your shoes seem to be exerting on your big toe? Those things hurt like the ****ens! I have wide feet and before would stubbornly ignore toe/toenail pain. Funnily enough, it wasn't until I got my first pedicure and the woman actually cut my toenails correctly that I stopped getting ingrowns. Maybe wider shoes will give your big toe a bit more room. Let us know when you find something that works for you.
