My shortness of breath occurred only with exertion such as exercise, walking uphill, going up stairs. It did not happen while I was resting. I had all the classic symptoms of Dermatomyositis, skin rash, muscle weakness, and ILD. Hopefully you don’t have Dermatomyositis, there are so many things that can cause shortness of breath. I would just continue to look for answers so you can get the proper diagnosis. Kathryn
