I have had swelling and pain in my left ankle and lower leg for many years. I was a dancer for 25 years and had some ankle surgery in 2011 and 2012 which involved ankle fusion and tendon repair. As time has gone on I am getting swelling in both ankles and now it goes up my legs and into my knees; sometimes even higher by the end of the day. I am a college professor and on the days I teach by the end of the day I almost cannot walk. I was told by one cardiologist I had venous insufficiency and he recommended a venous ablation. I sought a second opinion and he said this was not venous insufficiency but he offered no other explanation that I have not already ruled out. He said venous ablation could make the pain and swelling worse. Has anyone ever had this procedure and where can I go to get a trustworthy answer as to whether this is the problem or not? I have suffered with this for 10 years and it is getting increasingly worse such that I fear I am going to no longer be able to work. I am 62 and otherwise in good health.
