I have shortness of breath off and on, having it now its really uncomfortable like I have to yawn all the time and can only get 90% of breath.

But the weird thing is, I went for a walk today and even broke into a jog for a minute, and during this I didn't notice the shortness of breath at all.


Is shortness of breath only serious when it gets worse with exercise? I've had a load of tests about 2 years saying my heart was fine, but I've had no lung xrays or anything like that.

It seems to be worse when I lie down.

Can't understand this - right now I WANT to go and exercise more so it goes away again - just so confusing!!!

Can anyone advise???
