ive done some kind of, as it seems now, permanant damage to my shoulder.
whilst doing jo-dori with a particularly big strong kohai (the big friendly giant, lovely guy) he went to throw me and i was ready to take a nice forward roll away, at the last minute he accidentally stepped on my foot and put his whole weight down on me (he would weight about 1.5 times as much as me) whilst throwing me. being ready to take a forward roll, i ended up going head and shoulder first into the mat.
now my collar bone is bent (yes, bent!) and the joint where the collar bone sits on the shoulder pokes up unnaturally above it.
it looks strange, feels strange, but strangely enough doesnt affect my mobility in my arm.
