Thanks @colleenyoung. Glad you found us @zachsturgeon. I too found it difficult to explain to people this problem since it’s not a shortness of breath like you’re out of breath or even labored breathing, but more of an “air hunger” that is always present to some degree. And taking a deep breath may or may not satisfy it. Have you had various tests done; lung function, heart tests, blood work, etc? Mine had gotten better but use really just leveled off to a manageable level. I maintain moderate weight lifting exercise and breathing exercises to help at least maintain it. But I’m right with you, continuing to search for answers.
