I have a neuroma in my left foot. I "treat" it by being very careful with my shoe choices, wearing good insoles, putting metatarsal pads in my bike shoes. I love my Frogs because they are totally free float. My hip and knee are also very happy. I also stretch the leather of my shoes with a dowel or broom handle so my toes don't get any pressure. Lots of rest breaks when my foot needs it.
There are lots of exercises for the intrinsics of the foot to help support the area of the neuroma, but they aren't going to make the neuroma go away.
