Re: Exercise and Asthma? and a few other ?'s too
Have you been checked for VCD? That is normally tightness in the upper airways and can be anxiety related. A reliever inhaler would help it a little as well. The treatment for it is speech therapy, or helium and oxygen mixture when you are having a bad attack, it is important for you to get diagnosed properly as VCD can lead to the need to be vented (in bad cases) if it has not been diagnosed properly, as people think you are having an asthma attack and the treatment doesn't work.
As for the excersise thing, try not to worry, take it slowly and you will gradually get fitter and manage more. Try not to worry too much about your heart rate, and don't check it too often! Your body will let you know if you are over doing it, and the people at th gym seem to be a nice, caring bunch!
