Idiopathic Autoimmune Treatment For Symptom

I have an Idiopathic Autoimmune that was diagnosed by a Neurologist as the under lying cause of Small Fiber Neuropathy which is causing a dull burning pain in my right ear. This has always been accompanied with severe body chills. The frequency, duration and intensity for both the chills and ear pain have progressed together over the last 15 months and are now very severe. Neither my Neurologist nor my Primary Care Physician have ever recommended any course of action to calm these symptoms. Searches online detail the following for symptoms:

Steroids: Medications like prednisone are often used to reduce inflammation and suppress the immune system.

Immunosuppressive drugs: Drugs like azathioprine and cyclophosphamide help control the immune system's activity.

Biologics: These are newer medications that target specific parts of the immune system.

Plasma exchange and intravenous immunoglobulin (IVIG): These treatments are sometimes used for severe cases.

Has anyone had beneficial response from any of the above or something not listed.
