Neuropathy can be caused by gluten sensitivity (celiac disease), and gluten and other foods sensitivity is sometimes associated with RA as well. If this is something you haven't heard before, or investigated, I hope you will check out The Gluten File linked in my signature. If you scan the right bar, you will see a page on Neuropathy, and also Other Autoimmune disease which has some entries about RA, and maybe some other topics that might be applicable (like B vitamin deficiency, zonulin).

Here are just a few of the references you will find in The Gluten File. Of course, there are many many possible causes for neuropathy, but because you have rheumatoid arthritis I think following up on the possiblity of gluten sensitivity is worth considering.

"But the two things which are relevant to CD are nutrition and immunity. People with CD have nutritional deficits because of malabsorption; common causes of neuropathy are B12 deficiency, B1 deficiency, B6 deficiency, and Vitamin E deficiency. Neuropathies are also commonly caused by the immune system through autoimmune mechanisims."..."Latov commented that 20-25% of people with CD might have neuropathy."

You may also want to read about zonulin~ there is some new research about zonulin and celiac disease, that may apply to other autoimmune disease as well.

It is a lot of info from a lot of angles, but does show how there may be a connection between neuropathy, food sensitivity, nutritional deficiency, and other autoimmune disease.
