For The Last Three Days, Anytime I Walk, The Second

For the last three days, anytime I walk, the second toe on my right foot feels like a hot poker is stabbing the toe (the whole toe, not just the tip). It hurts to the point that I walk with my toes pointing up...I can't put pressure down on just that toe. I didn't bang it, hit it, or injure it at any time. It just started to hurt.
