I also have trouble breathing, my doctor met with me and noticed I have very shallow breathing. She has suggested that I exercise deep breathing 4-6 count in and 6-8 count on exhale. It is helping me considerably.

My husband has sarcoidoses which sounds a lot like what you have Theresa Baker 2

I have asthma so I walk in the Northgate Mall or at the YMCA on a treadmill, the Saharan dust or mold gets to me .

I have hypercapnia, a condition which most closely resembles COPD but which is not caused by by smoking, mold exposure, or any other lung injury. I retain CO2 which leaves less room for oxygen. Unfortunately the condition continues to worsen and I’m already to the point of it becoming difficult to finish a sentence without gasping for air several times.

The responses to this question lead me to wonder about my own breathing problems. The oxygen finger clip the professionals use shows no problem. Yet I am frequently out of breath with minimal activity. I have always been a mouth breather. My speech therapist is trying to help me use a breathing device.
