Several comments, speaking both as a former surgeon and prostatectomy patient:

1. Don't try to be a hero. Recovery is not a competitive sport. Being pain-free with improving continence does not mean you should return to normal levels of activity. There is lots of internal healing and re-arranging going on that you can't see or feel. Don't spend your body's energy resources on trying to resume your previous life ASAP. You've earned, and need, all the time off work your doctor prescribes. If retired, don't be embarrassed by daily 40-60 minute naps.

2. Keep an eye on those skin incisions. They'll start out red, swollen and tender, showing the body is sending healing fluid and cells to the fight. Also building new blood vessels to help the healing process. My key point: that's an indicator of what's happening internally in the surgical site. Over time the redness will fade, showing the repair internally is also completing.

3. Having advised caution, I also endorse GRADUAL return to previous levels of activity. My own experience @ age 74...walked daily after leaving hospital, also did prescribed physical therapy. Started swimming in three weeks. Began run/walking after 4 weeks, running a 5K in 30 minutes by 6.5 weeks. Hopped on an indoor bike after ten weeks, outside after twelve. But it took fully a year to return to previous levels of fitness.
