Swelling, numbness and tingling is more pronounced in left than right. Swelling leaves when leg is elevated. I am very active, walking, biking, hiking. Age 62. Problem has persisted for about 5 years. My family physician has offered tarsal tunnel, which I do not agree with. The foot numbness has some burning and tingling sensation. I have no back issues and am not diabetic. Numbness starts on the outsides of both knees and extends downward most pronounced in left foot and toes. Thank you.
