I have shortness of breath everyday.... I even have it when I go up the stairs and do some mild physical activity. I am started to get concerned now. At first I thought it was because I was low in iron, but I ma getting iron infusions and my SOB is not getting better.... I have it sometimes too when I am not even moving like right now as I type this.... I guess it's anxiety. I started lexapro a few days ago, I am going to give it a couple of weeks more... if it doesn't get better I guess I wil have to go to the doctor.... I am so sick and tired of going to doctors.
