@kdwhitfield Would you please explain your autoimmune features and elaborate on Cellcept? I have genetic pulmonary fibrosis, severe osteoporosis, and several digestive issues which are making some meds difficult to tolerate. I'm having blood work done soon to check for autoimmune disorders, specifically because of the osteoporosis, I think. Any info you can provide would be greatly appreciated. I couldn't tolerate Ofev and have recently had a sudden exacerbation of low oxygen levels and palpitations with mild exertion (I think due to a Prolia injection for the osteoporosis.) Only help has been rest and oxygen. Any suggestions?
