Best of luck with your health issues. I understand all to well the disruptions they cause. I firmly believe the more trips to the doctor, the lower your quality if life. After I had both knees replaced 11 years ago (I'm 71 now) I just underwent a revision (do over) surgery for my right knee. No fun! I'm trying to learn to walk again but after 5 months and lots of PT I still have very little faith in my right leg. While walking it sometimes refuses to step forward. I had one fall--lucky for me it was on the living room carpet. I can't afford to fall while crossing a parking lot--yikes!

Take care!
