Emptdepth,, Once RSD is chronic(which yours is) anytime there is an injury causing pain to your body the RSD will send more signals of pain from your brain. So if you amputate(which believe me i have considered until i researched) your foot the RSD will get worse and possibly spread to other areas. You also run the risk of phantom limb pain where your brain has had pain for so long that even when the limb is removed your brain still sends pain signals to a foot that isnt there. When blocks dont work anymore it means instead of sympathetic mediated pain it is now sympathetic independent pain. The brain was overloaded with pain signals so instead of sending messages thru normal pathways the brain has found other pathways to send pain. So removing your foot could actually cause RSD to spread to anyother limb. Unfortunately, like you, i still have times that i could cut off my arm because of pain but i know it wont help. momof4
