Thanks! I always hope some of what I have gone through saves someone a little time searching and floundering around. Nerve injury is kind of a weird thing to run down. I found the two peripheral nerve surgeons I consulted before my neuroma removal by googling, then combing through their training and looking to see who did lower extremity. Lots of hand people out there, foot not so much. Both Doctors I saw trained at the Washington Univeristy peripheral nerve fellowship program. They were both trained in microsurgery as well at Stanford and I forget where else. The head at Washington U, Susan Mackinnon is a big fan of scratch collapse so a lot of people from that program use it. I imagine if you hit a road block you could call the Peripheral Nerve Program at Washington U and ask if they have former fellows in Arizona.

Good search terms are "peripheral nerve surgeon Arizona" or "plastic surgery reconstruction". You want either a plastic surgeon who does lower extremity reconstruction or there are podiatrists who have undergone a fellowship for nerve surgery. They can be located through the website for Association of Extremity Nerve Surgeons. It did take some digging to find the right specialist, peripheral nerve isn't even a specialty so it takes time. for me it was worth it. I had a great surgeon with great training. Either one I consulted with could have done the surgery. I went with the one who was a little closer and with an easier follow up schedule since I had to travel for care. I still have pain, nerve surgery is rarely perfect, but having the neuroma removed made a huge difference for me. My CRPS came from a later procedure, wish I hadn't needed that one!

some people feel shakey on B vitamins, might try splitting the dose if you can
Good luck!
