So sorry that happened, sweetie. What a jerk! Clearly he is aggressive and obnoxious and a liability to your surgeon. Honestly, I'd make a formal complaint - you and hubby both, in writing - to your surgeon, especially because of this guy's attitude in front of your daughter. He keeps the guy employed - he needs to take responsibility. Imagine how many of this surgeon's patients have had less than optimal results (or have changed doctors) just because of this one idiot! Then I'd request a follow up appointment with your surgeon so that you can get the real scoop on your progress - you feeling good about how you're doing helps you maintain the positive attitude you need to kick some booty and get on with your new life!
More importantly, for you: remember, this guy does not get to define your recovery! As evidenced here, he knows nothing! Think of people who were in wheelchairs prior to this surgery who come out walking - honestly, the WHOLE POINT of doing it is to improve quality of life! So for him to say your ROM won't be any better than is was pre-op is just wrong. Maybe he meant your ROM before your hip started to get bad? (I usually try to give ppl the benefit of the doubt - it usually comes back to bite me LOL). Write your letter, get it out of your system, and then get on with the business of getting back to FABULOUS!!!
(Hey, if you need more encouragement, just browse around these recovery threads! Over and over again, people expressing how limited their lives were - the pain, the things they could no longer do - and the joy they now feel to be living a happy, healthy, pain-free life! Why should your experience be any different?)
