 Well, I think a couple things you want to look at. Now, the legs themselves, you talk about circulation, you can talk about nerve flow. There's a lot of things you can start looking at. And if they've done testing on it and really don't know what's going on, but you're feeling that every single day, I would go see one of two practitioners. I would see either a chiropractic physician that can lay things out for you and look at some testing from a little bit different perspective, non-surgical, look at the nerve flow,
