Hi Kathleen, my mom definitely had some of that with her IPF. She lives in a cold arid place and definitely had that with cold air more than warm. IPF makes the lungs brittle and fragile so I think it makes sense if you don’t have warm air making them more pliable, and humidity to keep them lubricated, to experience some pain. Definitely worth mentioning this symptom to your doctors though just be to sure it isn’t something else.
