When I take a big sigh, there is a tingle , but more than a simple tingle that goes down the inner thigh to my ankle. It started with just above the ankel, now goes all the way down. I am possibly having vein ablation in a few weeks; the cardiologist said this sounds like a nerve problem, not anything to do with the veins. Do you have any ideas? I also have some arthritis in that leg. And it feels sometimes like it refuses to bend properly.
