That even LOOKS painful.
I have a nerve problem with one of my feet (Morton's neuroma--self-diagnosed), and from what I hear, even surgery is unlikely to be effective. I'm putting up with it for now, but at some point I may have to consider doing something. I hope you're able to get some relief. I fortunately (or unfortunately--I should be getting more exercise) don't have to spend a lot of time on my feet. But if you do, it seems well worth getting it taken care of.
