Hi, I was wondering if the only medication you have been given is the Salbutamol nebuliser....have you no steroid preventer medication as well, such as a brown inhaler.
I find that I have to balance my preventer medication with my nebuliser or the blue inhaler, or else my cough, wheeze ,tight chest and shortness of breath gets worse.
The BLF helpline is open for advice during the working week, I think there have been a few delays recently though.
Have you a gp in your practice that specialises in respiratory complaints or a nurse, have you been referred to a specialist.?
In the mean time, many people on here, including me, find pursed lip breathing helpful for short periods of time......breath gently in through the nose with a relaxed diaphragm and then gently out of the mouth with pursed lips, a bit like a soft silent whistle. You can see it on You Tube too.
Shortness of breath can be caused by many things, I hope you get help soon.
