Or am I just a hypochondriac ? For about a week now, I ve been really out of breath . I can t even go up and down the stairs, or go across the house to answer the phone, and I get out of breath. Also, since yesterday, my upper right shoulder and the area around my collarbone has been hurting. I thought I may have just slept on it wrong. On the one hand, I was born with a hole in my heart and have always had a little bit of trouble because of it, nothing really noticeable, just that I wasn t ever as active as everyone else, and I ve been super stressed out lately.l On the other hand, I m only in my late 20 s, I am not overweight at all, etc. So, am I a hypochondriac, or should I get this checked out, could it be something to be concerned about ? I can t even eat without getting short of breath, if that doesn t sound silly.
