Graston or instrument assisted soft tissue is quite effective in a situation like this, but I am wondering if the neuroma was a symptom rather than the problem. I have seen neuromas mostly due to faulty gait patterns, asymmetry, short first toes, flat feet, core problems, restricted fascia in the lateral leg, etc.
One problem I always have with the diagnosis of this condition is the obsession with the site of pain, rather than the functional reason behind it. If you remove a neuroma, and the functional reason still exists, you will likely have the problem relapse. Sometimes a foot orthotics with a mortons toe extension and a metatarsal pad helps those who are asymmetrically built, and they can be used in a minimalist shoe so the shoe if desired in most cases.
I am not sure if that helps but my book, Cheating Mother Nature, what you need to know to beat chronic pain has a section in kinetic chains you may find quite helpful. Most people unfortunately, are uninformed about why things hurt and are hoping the professional they see are looking at their problem the right way. Unfortunately, unless you are knowledgeable, you may not get the result or see the practitioner that looks at you, and not just your symptom, the neuroma. You can get the book through Amazon and other booksellers but you should consider reading it.
I hope that helps
