The Morton’s neuroma is a metatarsalgia caused by hyperplasia (overgrowth) of a foot nerve between third and fourth metatarsal. It got its name from a doctor who in 1876 described the symptoms, Dr. Thomas G. Morton. It would be more correct to call it perineural fibrosis instead of neuroma, because it is caused by the constant touch of the metatarsus on that nerve. It is treated with cortisone injections or a simple surgery to remove the fibroid from the nerve.
