Renee,
I've had two BHR's in the last 5 months. I have an office job, but am up and around and out and about alot. I was out of the office 4-5 weeks both times, but probably could have been back in the office at 3-4 weeks. For me, the big issue was being ready to drive, especially with the right side. There seems to be a wide variation in how long people are restricted in their activities, depending upon the doctor and the individual, but I think 4-5 weeks on average seems reasonable, at least from my experience. BTW, I'm 48 and in reasonably decent shape. I would add that, while I have some stiffness (I'm 6 weeks post-op on my secod BHR), I have no pain and expect to be pretty much back to my "old self," including playing golf, by late summer or so. Having been in pain from OA for the last 5-7 years, this is quite a relief. Hope you're able to work things out.
Jim
