Again, some of this might be provider dependent. Not all may offer the On-Q. Perhaps you can reach out and ask what blocks the anesthesia department uses now. Your surgeon probably knows. Don't wait 3 weeks. Maybe it will help put your mind at ease. In my last month to 6 weeks pre-op I became very focused on strengthening my leg muscles and upper body, trying to eat heart healthy, and preparing mentally for the big event. I wish I found this forum earlier. The recovery guidelines put forth by the moderators are excellent!
