You've been through some serious surgeries. I am going to the doctor's office this coming Friday, it's about 3 weeks from the surgery. The knee is not doing well, don't really know why, lots of pain and inflammation there. I had problems with the knee before, he told me sometimes knee problems leads to hip problems. Hopefully he (or the assistant) can tell me. I'd hate, hate, hate to go through another surgery, but like the last one, the pain is so intense that it prohibits me from doing anything. So we'll see. Hope you also continually get better. Thanks for your experience.
