excessive air in esophagus

About a year ago when I was pregnant I started getting excessive air in my throat/esophagus. I do have bad reflux and take nexium which seems to keep it under control. I havent been able to chew gum for a year and a half because when I do I get so much air in my throat/esophagus. I have been to the gastro doc and they put the scope down my throat, didnt see anything and I did the barium swallow w/ no significant results. Doc says I dont know what to tell ya. I am getting very uncomfortable excessive air in my esophagus. It feels like I have a lump in my throat and cant swallow easily. I can also feel air in my throat area and cannot belch to get rid of it. It feels like very uncomfortable pressure in the throat area. I also get a little naseaus the longer it is trapped inside my throat. I belch, which helps, but I cannot get the air out of my esophagus. It makes me feel like I cant breath very well. So basically, I have excessive air in my throat and stomach and it is soooooo uncomfortable.... I take gas pills/tums but doesnt really help. Any ideas?
