I constantly find myself gulping for air,it seems as if I have an air bubble that prevents me from breathing,this I assume is coming from my abdominal area (maybe),this is occurring during the daytime ( I assume at night time also). My ears pop also when the bubble (not sure what else to call it). Anyone know what this might be,this has been going on for a while (years).

I have experience similar symptoms. When I exercise, I oftern start hiccupping.
