My complaint in August 2020 was that when I took a deep breath that I had minor pain in my lungs. My primary care doctor ordered a lung scan immediately which showed inflammation in my lungs. She then referred me to a great pulmonologist who diagnosed ILD the next month. He put me on steroids for a while, then discontinued the steroids and prescribed cellcept. I still take cellcept -- 500 mg twice a day. I feel great with no symptoms at all. My PFTs are normal. A very good pulmonologist is the key.
