J - We're close to the same amount out from our surgeries. I wouldn't worry too much. If things hurt, then rest. Early on in my recovery I was advised to back off the walking because my gait was so poor, and continuing to walk that way was reinforcing poor gait. I needed to correct my gait first, and then ramp up the walking. So I slowed up my long distance walking a couple of weeks. So what. It's the long term that counts.
I think it's very easy reading stories of what appear to be rapid recoveries and expect that you, too, will recover just as fast and well, if not faster. However, not all bodies are the same, and just because someone's abilities come back quickly doesn't mean they don't still experience soreness, stiffness, and other difficulties. They just might not be talking about them. In my case I can do so much more than before the surgery: walk for a 2-4 miles or more at a pop (haven't tested limits), swim at a good clip for 45 mins (more if I needed to), stand for a while, etc. Yet I still have deficits, and it's frustrating. Despite all the exercise and leg lifts my operated leg is still weak. I really notice this on hills. I can't use the ladder at the pool yet, I still use the lift. Believe it or not, I still can't tie my right shoe lace yet! My PT and I have been working on getting that ROM back, and it's almost there, but not quite yet. Most people can do this at this point. After a long walk I'm sore. My iliotibial bands still need work. Etcetera, etcetera, etcetera. It's like I'm a blend of things that improved rapidly, and others that just haven't. You're probably the same, with your own set of things that have improved along with things that are taking their time. Remember: recovery is not a race!
If your PT isn't working out for you, find another one. If some exercises are too much, just say no. Just don't forget that stretching and strengthening the muscles back to normal does hurt.
