I Have Had Edema In My Ankles For Over A

I have had edema in my ankles for over a year. A diruetic was no help. My cardiologist ran a bunch of tests. No problem with my heart. But he did find I had venal insufficiency, and performed procedures on both legs. It's now 4 months later, and edema continues. I have also spinal stenosis at L4-L5. Can spinal stenosis cause stenosis in ankles?
