Wow, who is telling you that? Fusing the symphysis should not require 12 weeks of in patient rehab. Geez, they took apart my hip and put it back together and I was in the hospital for 3 days.
I took a quick look at the literature and saw several options like this:
“Postoperatively, the patient is full weight bearing with limitation in activities for approximately 2 weeks, with then slow progression to activities as tolerated. Activities beyond those of daily living should be avoided that include exercise, weightlifting, and impact activities for the first 2 weeks. After 2 weeks, patients should advance these above activities slowly over the next 4 weeks with impact activities being the last to be incorporated. At 6 weeks postoperatively, symptoms should be improved and patients typically are able to return to their usual activities.”

I do agree that you’re expecting a lot, but I worry that you’ve not had the greatest assessment from an orthopedic perspective In your shoes, I’d push hard to see at least a couple surgeons who specialize in this field and understand–really understand–what your day to day looks like, and the level of activity you expect. You don’t have to suffer
