You might not have the same condition.
My son-in-law is a below-the-knee amputee (industrial accident). He's very active with an amputee support group. He's met quite a few amputees who had voluntary amputations, usually after years of struggling with surgeries and pain. They all say, "I wish I had done this (amputation) years ago." It seems weird but it's true.
That's not to say that's the solution for you. Most people do NOT need amputation.
Yes, sometimes we get too much information from the Net.
