One of the most caring doctors I've seen was a gastroenterologist. I wasn't seeing him because of the neuropathy, but he asked me a ton of questions about it and about what all testing I'd had done. I could tell he felt bad about all I'd been through, and also felt bad because I'd been referred to him for what he felt was a ridiculous reason. He was also the only one who has expressed concern about my low ferritin levels and decided to test me for silent celiac diseaase as that can cause both low ferritin and neuropathy. I was negative, but I can't tell you how nice it was to see doctor who actually expressed interest.
