Hi. I had esophageal cancer almost 6 years ago but I'm cancer free. I have difficulty breathing just like you by the sounds of it. I have most bad days and then a good one. If I do too much like walking, shopping I feel exhausted and have to rest for a day. If food gets lodged in my throat due to cancer surgery it's really difficult to breath. My doctors seem to be unconcerned but waiting for an appointment with a breathing specialist. I'm wondering if you have any ideas. Thanks Deb
