orthepaedic surgery

I was diagnosed with GBS in 1998. Everything came back except for my left foot. I have been walking on the side of my foot since, and now am planning to have surgery to realign my heel, etc. I am 57, and before GBS was active, including running. I have since gained 50 pounds, and am to the point where I cant walk without pain. I am hopeful that this will help, and am looking for input from others who may have had corrective surgery.
