My alternative to amputation worked. I still have my foot. We need to use our minds, before we let the doctors rush us into an amputation. I made it clear I would do whatever was necessary to save my foot, if at all possible. I'm glad I spoke up.
Amputation is very final.
Where there is ambiguity, uncertainty, disagreement, or even complexity, an outside specialist can provide important input. Maybe there is an alternative to radical procedures such as amputation. Maybe there is not. Either way, you can be that much more certain the step you take is the right one. Go ahead and ask for a second opinion.
