Hi bri,
I agree with Boomer, not only is every doctor different, but each surgery is different. Some folks have different weight bearing, so different recuperation instructions, some take longer, some not, and even for the same person, if they have both hips done, one may be treated completely differently due to the particulars of the OA or other issues that exist. So I wouldn't look to your brother or have him look to you for timing or type of recovery. Each time is different.
I had only aspirin for pain, it was enough, someone else may have more, different or longer treatment, yet both are 'right'. The only thing that matters is that you recover well, heal, train your muscles and mind right for your eventual return to full function with your hips. Anything else is just what you do to get there; it is important, but it's not your goal.
That is why I think PT is important. I would take the full set of PT, it makes the recovery better, exercises muscles and areas that I know for sure I didn't know how to strengthen well. I wouldn't have skipped it, it also made me feel like I was doing the right thing to reach my goals. You need that. I made quick progress too, but would not have gotten my hip to the strength it is now in my opinion.
