I have difficulty breathing lying down and my entire right side and lung feels like it is not working. When I try to exercise I pass out. I have had evert test under the sun and the doctors say it is emotional. I do not believe this. Any suggestions?
You have to define what you mean by "affects breathing".
While anything is possible, including the fact Sharon Stone might suddenly decide to propose to me, it is unlikely the nerve compression secondary to your stenosis affects your breathing. The pathways are such that either you will stop breathing if they are interrupted, or you will breath normally.
That being said it is not inconcievable. Just highly unlikely.
Of course you need a professional work-up from a physician. There are MANY possible causes of difficulty in breathing, and several options. There is no reason to continue suffering.
