hmm, some of what you mention could be a form or start of thoracic outlet syndrome... whiplash, and other car accidents can be a factor in cases of it.

Have you ever done chiropractic? {expert one of course}
You might need a c1/c2 upper cervical adjustment and most likely the whole spine and some PT sessions with soft tissue work.

let me know if you want more info or the useful sticky on the TOS forum post # 1 has chiro, triggerpoint, bodywork- all kinds of helpful info.

the feet and leg stuff could be tied in to misalignments only lower in the spine.
