I have had many days where I am just screaming (to myself) "JUST CUT IT OFF!!"
When I finally calm down, I realize that is not the answer. As mslday said, there could be worse consequences. Remember that the pain is really in the entire nervous system, including your brain. We "think" it is in our hand, or leg, or wherever, but the pain is really everywhere.
I know when I am feeling that amputation is the answer, I just need to rant, rave, cry, and get past it.
I really wish you well. I hope you can find a pain management doctor to at least get things a little more tolerable.
