Dislocated or Sprained???

Well yesterday I realized that I could not bend the toe next to my big toe on my right foot and that it was swollen but it did not "hurt" per se. Today I can bend it with concentration but it's still swollen. Soooo I assume it's not broken or it would hurt a heck of a lot more, and that leaves me with either it was slightly dislocated and somehow popped back into place over night to bend this morning, OR it was just sprained and now that the swelling is down it bends more easily, though still slightly swollen. Time will tell I suppose.
