I'm curious about the small fiber neuropathy in your toes you mentioned. I was diagnosed with severe sarcoidosis a few years ago, and am currently taking azathioprine along with adalimumab. As far as I know the suppression is working regarding the sarcoidosis, although I've been having trouble with viral infections lingering a long time. Recently I've been noticing some burning and numbness in my toes, and your post made me realize it's most certainly nerve related.
