I have exactly the same problem you are having. It happen last winter(Jan 2007) when I went off a jump snowboarding. my toe felt tense like it did not want to bend in my boot when I was getting air off the jump. Then I landed and it force my toe to bend in the boot(a normal bend but it didn't want to bend) tendon snapped or popped and it hurt for about a week. I can feel it randomly when I bend my toes a certain way. never went to the doctor. but I just pulled it again tonight snowboarding this year, so the pain will be there for probably a week. After it heals again I will still get the exact same sharp pian in the same place AROUND that toe and in the end of the toe really hard to pin point. I might just go to the doctor tomorrow. THIS SUCKS!!!
