That looks like it hurt, but physical therapy isn't that bad, I've been going since I was in the 6th grade, I messed up my shoulders pretty badly playing waterpolo, and weight lifting. Usually you'll just go in twice a week for about an hour or so each visit. OHH but the best part is the electro-therapy!!! Just make sure you tell them when it hurts, my I didn't and they set it up REALLY high, and then my whole body went into spasms and I couldn't talk cause I was jolting around so much and then the girl came in and saw me and then she was like, "Oh no, you should have told me something." But it wasn't comfortable at all...
Just make sure you do what they say for you to do. exercises and all, cause they can tell.
