Hi @kenc, I think a lot of us have been successfully treated for an autoimmune deficiency considering there are many different conditions. Prednisone returned my PMR to remission and I hope it stays there 🙂. Mental fuzziness can also be due to some of the medications being used to treat some of the conditions. Here's some information that talks a little about it.

"Is there a cure for autoimmune deficiency? - Treatments can't cure autoimmune diseases, but they can control the overactive immune response and bring down inflammation or at least reduce pain and inflammation." -- Autoimmune Diseases: Types, Symptoms, Causes, and More: https://www.healthline.com/health/autoimmune-disorders

Are you currently on any treatments but still having some pain and inflammation?
