Scared to get the surgery done

I’ve had a pretty severe MN in my left foot for about 5 years now. It limits my activity and I have to be pretty careful about my footwear. Regardless of what I wear, I can’t put pressure on it for longer than a couple hours. My job involves a lot of walking, unfortunately.

I’ve done, I think, 7 of the alcohol injections, to no effect. My doctor is preparing me for the surgery.

Reading about it has me really scared. An 80% success rate is not what I was hoping for. There’s not much else I can do, though, if I ever want full use of my foot back.

Worst thing is I can feel a mild popping on my other foot so I think I have the start of one there, too. I’m going to, hopefully, try to nip that one before it gets as serious.

Can anyone talk me up a little and ease my concerns about the surgery?
