I also went back on pred a couple days ago to 40mg. Breathing and energy and coughing up mucus was getting worse. I went for labs a couple days ago as well and the WBCs were up to 11.8 and the CRP was up to 35. So something is going on. I suspect still part of a mini flare and I might need another dose of RTX or it is a lung infection. I'm leaning towards a lung infection. Thankfully I see my new lung doc next week.
