Hi,
I can't really comment of the feet part of the problem..
but possibly your hand/arms problem might be based higher up in the neck/shoulder/collar bone/top rib/pec minor area....??
have your DC check all those places.
And to check for trigger points in the scalenes & upper back - those are pesky for referring pain to other places.

You might want to skim thru our Thoracic outlet syndrome {TOS} forum & the useful stickys there - to see if any of that might apply.

Your hand symptoms sounded very familiar to me.

I had some RSI injuries & neck/shoulder strains that eventually became a chronic TOS type thing..
At the beginning {also work comp}
My PT and docs mainly focused on the pain & sx were in my hands and not the total of all my other symptoms.
So it took me reading online & learning for myself -and finding a really good DC & adv PT guy- to find the real causes of my failure to fully recover.
I would recover to a point when off work but as soon as I returned to normal tasks - symptoms would all come back quickly.

so check out the stickys - post #1 has a crash course of links on TOS and therapies.
