Re: Please help - got injured badly in aikido 2 days ago.worried I can't do aikido fu
Yay! That's great news. :-)
A trick I've used for taking off t-shirts (post-shoulder-surgery, and after injuring mine) is to lean forward and let your arm hang "up" over your head - like raising your arm, but upside down, so you aren't using muscles to do it.
To put a t-shirt on, stand normally, put the hand on the injured side into the arm hole, and pull the shirt up to your armpit, and then put it over your head and other arm, again keeping the injured side completely relaxed.
By the way, both of my shoulders are "sprung" (what my orthopedic guy called that bump)... Doesn't seem to cause me any trouble. :-)
