At 44 years, diagnosed 2 yrs ago, I too have tried to see the positive in that I have travelled, fallen in love and had a rewarding career. . .you really do just have to acknowledge the positives.
Empty, I agree with Finz. . . please don't do it!!! I have often thought about it myself except that I have this monster in both of my legs, so amputation would see me perched on a skateboard using my arms for motion!!! Besides, I am way too much of a shoe addict not to have feet!!
Since most RSD cases are a direct result of some form of trauma, the body might not acknowledge the amputation as a helpful medical procedure but rather another trauma, which could cause it to spread rapidly. I too have heard of the 'phantom pain.'
In my opinion, the risk is too high. . .
take care,

Kelly
