rough road -- many questions

Today, was a more challenging day than I expected. Physical Therapy was difficult. My hip, 20months post surgery, was not terribly happy, nor were my knees. I had a long hard talk with the doctor's nurse and my PT team, and we are getting closer, it seems to let go of the necrotic hip. That was really tough to hear, although, I, somewhere in my heart know that is what may be necessary. (I don't even want to say it outloud).
