Rob, my toe was probably brussed real bad or maybe even (hairline) fractured. Then again, it is my little toe, they cannot do much about it, not put a cast around it or splint it. I contemplated going to my physician but he would probably confirm my diagnosis and tell me to keep on moving without doing extreme things. O yes, maybe I should mention that I have some experiance with broken/brussed bones (my recovery time and long-term healing are quite good) and a little medical training. Furthermore, my teacher is a trained and very experienced sports masseur. If he thinks someone is doing something they should not be doing with their body he probably pick them up and carry them of the mat himself if they wouldn't go voluntarily.
Thanks for the concern though, at least if you meant me, otherwise sorry for the non-related chit-chat.
