Hello, i also have an autoimmune disease that was difficult to diagnose. Once an MRI was done which showed lesions on my brain, i went to a neurologist. But, yes, rheumatologists are frequently the doctors to go to. Start by keeping a journal of all the symptoms that bother you and how frequently they occur. Keep this journal to share with a doctor. Diagnosing autoimmune diseases s a very long and difficult process, I’m afraid. I recommend reading the discussions which Colleen posted.
