I’m sorry you’re going through this, but I can relate. I also have pain& stiffness after 10 weeks, though my orthopedist says I’m doing fine. However, I’m also having pain in my right SI joint, which I never had before surgery. It really hurts to walk, which complicates everything. I have been trying to take in more protein, usually one Ensure every day. For a while, I had no appetite, and lost 13 pounds, but my appetite is coming back. I just wish the lightheadedness, weakness, pain and stiffness would resolve.
With regard to increasing ROM, I found it helpful to use a strap, and pull my lower leg as far in and close to my thigh as possible. I do this 20x, three times a day.
I’m sure you’re doing PT also, it’s definitely a slow process, I’ve found.
And yes, I also have these unexpected, crying jags, which I never did before, very uncharacteristic for me, but I can’t seem to stop it, just too depressed, I guess.
