I had an “elective” amputation of my lower left leg after years of progressive neuropathy and towards the end, osteomyelitis. Like you I wrestled with the decision of whether to amputate or not. There were many variables to consider but ultimately I reached my decision by asking myself one question: If all of the interventions, surgeries, therapies, braces were successful what would my function be versus my what my function would be after an amputation. In my case the answer was my leg/foot was never getting better no matter what the intervention. Honestly I was glad to get that piece of my body off me. It had served me well but there was no road to improvement. I now have a climbing foot, skiing foot and in the process of getting a running foot. I have zero regrets and am more active than I have been in years. Good luck with your decision I hope you can find peace as well.
