If your arm allready feels pretty good then you are pretty damned lucky. My arm was strapped to my side for 2 weeks, then I had about a month of a sling, then a couple months of rehab starting with just hanging my arm down and swinging it gently side-side...
But, Mine was a traumatic dislocation, an attempt was made to reduce it in the field, with no avail and it landed me at Wilford Hall. Long story short 8 hours of Surgery later... It still hurt like hell... For a few weeks anyway.
It's still not right, I don't have full range of motion nor sensation along the interior portion of my and my two little fingers tingle...
So I guess my point is You should heal fine in no time and strength will return. Biggest help out there is competent physical therapy stick to it and you'll be GTG.
