Did I cut the circulation to my toe?

I need black shoes to wear to work. I bought these black flats by Sam Edelman. I wore them for about 3 hours straight at first. I work somewhere that requires a lot of walking. I took them off for my break and had to wear them again for another 3 hrs. It hurt so much that I was limping all over the place. I had too deep red lines, one under my big toe and one under my pinky toe. Once I got home I notice my the LEFT SIDE, of my RIGHT big toe felt funny. It doesn't look discoloured. But when I touch it theres a slight fuzzy feeling. I pinched it and didn't feel much. Does anyone know what happened? And HOW I can restore it back to normal???
