How To Treat Severe Pain In Right Leg While Suffering From Neuropathy?

My wife & I are both 84 living in Windsor CO/FortCollins CO altitude approx 5,000 ft. Thinking of moving to Estes Park CO altitude 7500 ft, I am in good health, my wife has several problems and takes the flwg meds, Aspirin 81 mg daily, Durezol 0.05 % 1gtt 4 X day, Restasis 0.05% 2 X day, Spiriva 18 MCG 1 capsule day, Symbicort 160-4.5 MCG/ACT 2 twice day, TraMADol 50MG 1 2 X day. She had a mild TIA about 2 yrs ago, has Nuropathy in both feet and legs (not diapedic), a serious balance problem. She has had 3 corneal transplants in the right eye with no success which adds to her balance problem. Her right leg gives her a lot of pain and she needs to use a walker. We have been to about 12-15 different Doctors with no help and she does t even want to to consider seeing another, we would just like to live our life out in Estes Park, if we could. Your comments would be appreciated
