Mysterious finger swelling....

So today it was howling, i think gusts were up near 40mph, and not being able to ski i decided to break out my windboard with a friend, longboard with a windsurfing sail atteched. So we drove down to the marina which has a huge lot right on the shore. Shit was legit laping around there for 30 minuted or so. Prety cold but not to bad. All of the sudden after i sat down to film for a little, i felt my right fingers get stiff, i just figured it was the cold and didnt even bother looking at them, just put the camera down and shoved my hands in my pockets to get warm. After about a minute of that i realized i couldnt bend my fingers. I look at my right hand and my fingers were HUGE. I mean the middle section of my middle finger was an inch across. I couldnt bend them but i wasnt in any pain. They are almost back to normal nowbut still suck a wierd experiance, ever happen to anyone else?
