Wow...that is one brutal surgery... I found PICTURES of it on the net!
Whatever process led you to that procedure, must still be going on, and causing trouble.

Once the feet are affected I think by ANYTHING, you have constant woe.
If this is where your pain is concentrated, you can try local solutions.
Compounded topical transdermal gels with ketorlac, ketamine, gabapentin, may help. People with RSD use them, but so do arthritics.
Also Lidoderm patches can be cut and creatively applied on your foot (I prefer the top of the foot for my pain/burning) for relief. I choose locations to interrupt signals, and find application to the exact site of pain is less effective.

I have broken sesamoids myself and am avoiding surgery. I know people who have had it and relief from removal is not good with that surgery. So when I flare due to some foot movements/mistakes I use patches and also the OTC Salonpas. I haven't tried the new patch Flector yet (diclofenac patch), since my Salonpas work well for me and are MUCH less expensive.

Burning in the foot can be temporarily blocked by high concentration menthol products. Biofreeze is what I was given, but there are others. The menthol selectively stimulates cold receptors and overrides the heat ones that are
firing too much.

Brian and I use high quality neodymium magnets for severe pain. I used one when I broke my toe (a big boulder crushed my toe while I was working in the garden). It had two breaks, and was badly bruised. Magnets block pain very well, IF you get the right type, a very strong one and apply them to the right place (over a nerve path). I did not find
shoe magnet inserts valuable at all (not strong enough). You need at least 5000 to 6000 gauss, and the ones I found were 10,000 gauss.

This is an example of EXPENSIVE:

This is AFFORDABLE...

I don't like using them on the head, as they can cause dizziness if you have any ear problems.

One really strong magnet per foot applied over the nerve distribution to the toes will do it. (it does for me).
I use Micropore tape, and moleskin on the metalic side touching the skin.
My podiatrist suggested the moleskin (he uses magnets all the time) to prevent "magnet burn". And some people are allergic to nickel.
People laugh, but they do work. When you are in pain, you will try ANYTHING.

Topical solutions if you can get them to work, are the best IMO.

And if you have only mostly burning... please try Thiamine 200-300mg/day divided doses, or 150mg to 300mg of Benfotiamine. This intervention is very powerful for people with dehydrogenase failures, which are more common than many doctors think. Thiamine can be depleted by drug therapies (most antibiotics, diuretics, theophylline, digoxin) and use of alcohol and/or disufuram and/or Flagyl interfere with this metabolic system. Benfotiamine just came down in price and I have switched to it...with much better results than the old thiamine I was using. There are many papers now on PubMed showing improvements in PN with it.
