I've been experiencing some burning pain on the top of the outside edge of my right foot, about halfway between the ends of my foot. I've been searching online and was thinking about Morton's Neuroma as a possible cause, but my pain isn't really near my toes or the ball of my foot. I've been to a podiatrist, who thought the nerve was inflamed and taped up my foot and put me on anti-inflammatories. The anti-inflammatories seemed to work well enough (pain was probably 80% gone), but when I went off of them the burning pain returned. Sometimes it hurts when I walk and sometimes it hurts when I'm doing nothing at all. I can't recreate the pain by pressing on the area and it doesn't appear to be swollen at all.
My real concern is that I'm set to begin a 2100+ mile thru-hike of the Appalachian Trail in a couple of months and I'd like to solve the mystery before I leave. I don't want to make the problem worse and/or let it stop me from hiking.
A little about my feet: I've been told that I have high arches. The outer edges of my shoes always wear faster than the inside edge because I guess I tend to walk with more pressure on the outer edges of my shoes.
Does anyone have any ideas on what could be causing this or advice on remedies? I could see another podiatrist if necessary (didn't like mine too much), but time and money are short and I thought I'd see if you had any advice before going that route.
