Major setback

I had that same surgery done in January. I wore that stupid cast/sling for two days, then threw it in the trash. I was out of work for 3 weeks, then went back but I played with my truck in the garage the whole time. Didn't do much lifting but I moved it -- a lot, which is what they tell you NOT to do. I replaced speakers, clay bared and waxed the whole thing etc.
I started therapy at the 4 week mark, and the therapist told me she's never seen anyone 4 weeks post op that had the range of movement that I did.
After 2 weeks of therapy she told me I have more range than most people that didn't have surgery at all. I checked myself out of therapy at the 5 week mark.
Long story short, you gotta move it. Little at first, but move it.
BTW, my crappy insurance left me with $3800.00 in med bills for my part of it, mostly the therapy, and it was a $40.00 copay (twice a week) for the 5 weeks I went to it..
Almost a year later, I can't feel any pain or movement restrictions, although it doesn't seem as strong as it was before the surgery. I guess I'll have to live with that.
Good Luck to you!
