I finally seemed to have solved my Morton's neuroma problem, at least for now. I did two major things: first, I got it injected again with the cortosteroid by a very good soft tissue orthopedic doctor (not the podiatrist who'd injected it the first two times). He had also ultrasounded my foot and diagnosed the sesmoiditis. Second, he referred me to a pedorthist, who made me throw out half my shoes and made orthotic inserts for the rest of them. Basically, they both said that I can't wear high spike heels, flipflops, or anything else that is unsupportive. He put me in a stiffer running shoe and also suggested a brand of shoes/boots called "El Naturalista". The doctor also said I should do foot exercises, and wear supportive shoes even when I am walking around the house. Anyway, this was back in November and my foot has been fine since then. I can even feel the toe that had been numb for the past three years.
