I'm not sure about your symptoms, but I can say with confidence that GERD can most definitely cause lung issues. I have asthma, and my lungs were extremely sensitive to even small amounts of reflux.
My lungs were in horrible condition as a result of GERD, and I waited far too long for surgery. Thankfully the surgery worked well, and my lungs improved 100%.
People with severe GERD/aspiration reflux can get very severe lung symptoms, even when they don't have asthma to begin with. Untreated, severe reflux can actually cause lung damage/COPD.
Again, I'm not suggesting that your breathing issues are caused by GERD, however in response to your question, my answer is absolutely, yes!
Hope you feel better soon!
