Here is my experience with shoulder surgery on Jan 2. Bar none the worst recovery I have ever been through and that includes falling out of a tree and breaking my back and wrist.
I just passed the 6 month post op phase. I have never stopped doing rehab and did 6 hours a day for the first month and a half, 4 of those with a passive motion machine.
I started out with 25lb bow at the three month stage, shooting wasn't fun. Moved up to a 38lb bow at 4 months, 45 LB bow at 5 months and will mix shooting the 45 pounder and my normal 54 pounder today. My surgery was on my right or drawing arm, if it had been on my bow arm I would probably not be shooting much at all at this stage.
I do rehab with weights at the gym three days a week and mild rehab at home 3 days a week.
I had lost a bunch of mobility and had adhesive capsulitis so I gritted my teeth a couple weeks ago and broke myself loose by forcing my arm back over my head with my good arm, it wasn't a fun thing to do. Since I broke myself loose I am progressing again and can see the light at the end of the tunnel now. I don't have any pain free movements with my arm but the pain is letting up some now. My aggressive rehab keeps everything inflamed.
Most of my friends who have had this surgery say it took them 8 or 9 months to start feeling close to normal again.
