Thank You All
I'll go see my doctor again, because my shoulder still bothers me a little. I'll keep practicing but with care (Not plomeling myself from 6 and a hafl feet
but from 20 inches from the floor
). I tried the sitting ukemi advise in my office (I closed the door so no one could see me and think I'm weird
) and it help. It didn't hurt and it was a good-smooth roll on a hard floor. I'll try this weekend in class and other variants (Both knees are good but I had try before with one knee on the floor and it also is efecctive). My usually nage is very understanding with my injury and is gentle with the technique on that shoulder.
I may have damage it, but I will be careful not to damage it anymore.
