I went to the dr on Wednesday and he gave me a shot in my knee. I am feeling so much better. Now working on the sciatic nerve on the right hip. It is so great to be able to walk and work out in the pool now. He said the treadmill was too hard on the knees but that I could use the recumbent bike and the elliptical. So off I go 35 minutes swimming and 5 minutes walking in the pool hope to be able to do more very soon.
