Today, just before lunch, I took part in my final physical therapy session for my knees. Over the past eight sessions, my knees have much improved. The pain of sitting in one position for prolonged periods of time has almost been eliminated. My therapist tells me that I need to continue my at-home exercises for at least another few months so that the symptoms don't recur, then I can start to slack off. I'm really, really happy with my progress. I'm especially happy that surgery wasn't necessary to correct the problem.
