Hi Lion, I'm sorry you are having such a hard time. I know it can be depressing having yet another symptom come up. I'm the queen of lung problems around here so my first instanct is to tell you to see your doctor and make sure you don't have bronchitis or pneumonia or somthing like that. If you don't than you should see a pulmonologist ASAP. If you are having problems with your lungs due to lupus the sooner they catch it the better it will be for you to protect your lungs. Trust me you need our lungs for everything even if we tend to take them for granted at times.
Regarding the breathing when you are it makes perfectly good sense to me. It feels like you are getting more oxygen when you breath through your mouth. The only problem with that is you may be filling your lungs with oxygen but you aren't getting the right balance of carbon dioxide. When I have a bad attack my first instanct is to try to breath fast and deep through my mouth. That is the absolute worse thing I can do. I have to force myself to breath through my nose and purse my lips to breath out. Also if you aren't breathing properly you will get tired more easily.
Please get it checked out as soon as you can and please let us know
