SUCKS!!!!!!!!!!!!!!! OMG today was my first day and it was terrible. My knee hurts more now then it did when I went in.. They ask "does that hurt?" Well of course it hurts what the heck do you think it would feel like? LOL These first couple of weeks are gonna suck...I have it 3 times a week. The physical therapist was like "we have our work cut out for us" duh!
