My other half has psoriatic, rheumatic, and osteo forms of arthritis. With replaced knees, and joints not working, a specialist has been seen for years. The x-rays, blood tests, and opthamologist exams in relation to medications are 2 to 4 times a year.
My arthritis and bursitis are at a much lower level. You appear to be headed in the correct direction. Ask the rheumatologist to understand the RF factor. Put your questions together, before seeing the specialist.

Hey i just googled that and it's actually a few things that could make it spike. Autoimmune disorders among them.

I have a friend who has that. She's not epileptic but is in the process of getting it taken care of. I can ask her and let you know.

I read in the Journal of Neurology that the Dutch were having success treating Epilepsy like an autoimmune condition which is along the lines of RF

I know this was posted forever ago, however i just saw it. I have RA and Fibro, chronic Migraines, and currently being tested for EOE as well as otger lovely stuff but those are wonderful autoimmune stuff im dealing with. I wondered if all the pain would cause the seizures. Ive had epileptic and non epilectic seizures. My body is just trying to kill me lol
