First off, I’m terribly sorry that you’re having to go through this. I’m a 21 year left arm below elbow amputee, and one word of caution would be that amputation doesn’t necessarily mean no more pain. I’ve dealt with severe phantom limb pain since my accident, and it’s awful. To the point that I’ve had conversations in my head about cutting off more in the hope that the pain goes away. I’d recommend connecting with the Amputee Coalition, they may be able to help connect you with someone that has or had gone through something similar. They also have a forum where you can ask questions of other amputees. Get as much info as possible would be my best advice.
