I would make sure you talk to as many people as you can before you do anything.
I have a GSW to my right thigh and have nerve damage to my lower leg. You don't know how many days and nights I have wished they had just taken my leg in Iraq. The pain I go thru may not be the same as yours but I do understand. I have a little girl who I will never run with. I am learning to live with what I have and to be thankful for it. I am not saying don't do it but am just saying make sure you ask all the questions before.
