For about a year now, often during inhaling I feel short of breath .This has been happening from time to time and if I remember correctly, it happened when I was a bit younger too. I feel stiffness at the center of the chest, between the breasts; especially the breathing becomes tough when in bed (if I don't sleep on my back). The doctor whom I approached sort of brushed me off and suggested some tests. The x-ray test was fine, but another test was cancelled due to a cold which later I wasn’t able to reschedule. I doubt this could be asthma or stress because I’m a highly stressed person. It’s really upsetting because I have a hard time getting someone to not ignore me about it. It didn’t happen all of a sudden; it has been remaining there most of the time. My mother suffers from asthma. I really doubt that this could be stress (as someone had said to me) because it had been for a long period of time. I was also told that if that is the problem it could be scary but not dangerous.
