I'm a 32 year old male with a reasonable level of general fitness.
Over the past few years I have been aware of occasional shortness of breath, which is getting more frequent (almost chronic) and severe. The symptoms include a feeling that I'm often not getting a 'satisfying' breath - like a 'half yawn' - and the need to yawn a lot, especially when in a sitting or lying position.
I have mentioned this to a GP in the past but he dismissed it as a symptom of being slightly overweight (I am 6' and 14st, the finely toned body of the office worker :-) and suggested more exercise. I accepted this for a few years but more recently, despite being an occasional jogger capable of doing the odd 10K run, this appears to be getting worse.
On the subject of exercise - I initially questioned whether this might all be in my mind as I am capable of running a reasonable distance, though I am aware that I don't have the stamina or speed of my co-runners, despite having been running longer than many. I tend to find progress in the running very difficult and wonder if this too could point to something more serious.
For information, I am and have always been a non-smoker, drink moderately and sensibly, and eat a balanced, mainly vegetarian diet. The birth of my baby son last year has prompted me to take my own well-being more seriously so that I can be there for him, hence my concerns.
Has anyone else any similar experience of these kinds of symptoms, despite otherwise having a reasonable level of fitness and health?
