Wow...you wrecked that thing when you fell. You didn't fall off a tall building did you? :-)
I meant to mention this in last response. I can't remember exactly how long it was before I started therapy but I know it wasn't anywhere close to 4 weeks. I'm thinking it was well within ten days and I'm thinking more like a week. I remember thinking when they told me when it would start, "that's awfully quick."
Could be they determine when you start therapy by how intensive the repair surgery was.
As for possibly tearing it loose...I doubt they could do anything about that for a while. They'd probably give everything a chance to heal up before they went back in. I could be wrong about this too, but it seems like I remember one surgeon telling me they can't/don't like to put people under very close in time to the last time.
Being as I'm not even a doctor I would suggest you mention it to your doctor and see what he/she thinks.
Hopefully, it didn't come loose. Check with the doctor.
Repeat after me. I have no left arm...I have no left arm. If you need to push yourself out from in front of a fast moving train with you left arm...take the hit. :-))
Keep us informed as to progress and good luck!
