GERD, excessive burping, breathing difficulty, plz read

And as cough stopped, belching came back. As for the breathing problem , i suddenly started having difficulty in breathing, it is like having a constant feeling of suffocation, can't take deep breath and feel as my body and brain aren't getting enough oxygen. Narrowing of esophagus has been diagnosed in a test but is it the only reason. The sound in breath increases at night and early morning. The worst part, now i can't sleep because as i start falling asleep i suddenly feel my breathing has stopped as i wake trying to take deep breaths, my legs, arms and head feel numb. I hope this isn't sleep apnea. And when i wake like this i have to force out many belches to become able to take deep and full breath, yes, weird but true.
