I eat mints!
Oh...there are stupid exercises you are supposed to do.
Like...bend over slightly and move your arm and try to move your arm forward and backwards. And wall crawls and and carp with towels.
I will look for the site that has the exercises that I had found and get back to you.
It is a very slow process. You can't force it.
PT would be nice and they would tell you what to be doing. Esp if you get a cute one!
