Hi, @lturn9. I am so sorry to hear about the problems you are experiencing. It's so baffling to think that orthopedic surgeons can do such things as shortening the bone without realizing how that would affect the patient afterwards. It's as if they are operating in a vacuum without awareness of the aftermath.
My sister was convinced that her leg length discrepancy brought on groin pains. But the ortho docs she consulted attribute those new pains to the need for another replacement -- this time her hip.
She also was told that what one doc measured as leg length discrepancy is actually just "perceived" since she has knock knees. Very confusing. But she has signed up for hip replacement next week.
For your situation, have you looked into MLS Laser Therapy for your neuropathy (that is if you meant diabetic neuropathy in your feet). Apparently the laser made by that company has shown that it improves that condition -- at least that's what its literature says:

I have been getting MLS laser therapy from a chiropractor near me. It has helped pain in various areas because of my deteriorated hip. He also uses it to hit trigger points where my muscles are bunched.
As far as your leg length problem, have you looked into Feldenkrais? It's a way of movement that rewires your brain to allow your body to compensate and move differently.
Also, would stretching those muscles on the shorter leg - under the guidance of someone who might know specialized PT (perhaps for folks who have muscle diseases) help?
I wish you HOPE. Don't despair.
So far I am putting up with collapsed hip joint (which still does not hurt) but having more problems with all the compensating parts (ankle, back, knees, etc,)
