I haven't had surgery yet, but I wanted to let you know I had my sesamoid bone removed from my foot on 2/8 and tendons/ligaments re-routed as well. I'm non-weight bearing until further notice and I understand your concerns. I don't have much advice, just wanted to tell you you're not alone. So far I've only met with a surgeon, so I have a ways to go before being approved and all. I understand where your surgeon said it was possible to do it, but personally I would like to recover from my current surgery issues before moving on to another surgery. It would just ease my mind and make me less nervous to know I'm able to walk, get around, and only dealing with one thing at a time. Best of luck on your journey!
