You want to try to avoid foot surgery, if suggested for neuroma or tarsal tunnel, until the low back component has been worked on considerably. But, you still need to treat the foot locally.
Golden Rule of Foot: Treat the Low Back Nerve Component First to see what the Role in the Foot Pain.
You are so right to want a team approach. Typically, this is a physiatrist, who can work with the medicine/epidural side, but knows what the podiatrist is doing, and what the neurosurgeon has to offer.
You are in a nervous system overload right now. You should maximize support to the foot and low back (orthotics, foot strengthening/taping, core strengthening, back braces), and ways to minimize nervous irritability (oral meds, topical meds, warm soaks, neural flossing,etc.). I never recommend avoiding medications in this scenario, since you have to get the nervous system calmed down, and it can take a long while, getting the medications right.
Definitely, the role of orthotic devices to stabilize your lower extremity, and lifts if you have a short leg, are a no-brainer to me. Find out who makes the best orthotics in your area. Have your doc prescribe a Standing AP Pelvic Xray to document the leg length difference standing (I have some posts in my blog on this). Treatment of a short leg is Back Pain 101 to me. Most definitely recommend surgery for the back if the nerve injury is causing weakness in your legs, but waiting a month or two to get orthotics that make your feet function symmetrically and lifts for any short leg make help considerably.
I sure hope this helps somewhat. Rich
