If it's very purple and such, I really do advise seeing a doctor. But, until you do, tape the toe to a larger toe using fabric medical tape (it breathes well, and will not trap moisture), and where solid, comfortable, closed toe shoes. Open toe shoes have a higher chance of leaving your toe open to further injury. If you do not own a pair of closed toe shoes that fit well with just a little tape, it means your shoes do not fit at to begin with, and you need a new pair anyway.
But, to be honest, the doctor will probably glance at it, maybe give you an x-ray, and give you some pain meds before sending you on your way. I've shattered the arches in both my feet, broken six toes, torn ligaments and muscles to all hell, and severed more than a few nerves in my time (ballet+gymnastics+karate=bad combination for health), and I have never had a doctor do anything more than give me some pain meds. Though they were really good pain meds, I must admit. :roflhard:
I do hope your toe feels better soon, though. :hug:
