Well, here's my update. Went to the doctor yesterday, I need total knee replacements on both knees, but the doctor won't even touch me for four years. that's because of all the infections I have had in the last ten years. He said if I stay well for 4 years then he will do the surgery.
so, I am on a quest to stay well for 4 years. I am on crutches at times and still use the cane for my balance. It's going to be a long 4 years. Tom is going to be on blood thinners for the rest of his life, so we have to be careful on what we do.
