Something in my throat and inabilty to burp

[newjoseca]

I had a Nissen fundoplication 9 months ago. Everything was fine until the last month that i started having a sensation in my throat like an air bubble that i cannot eject. I feel it 24/7 and it had become an aweful nuisance. I had a rinoendoscopy, endoscopy, an esophagogram and there is nothing wrong. I don't know why this happenned if i felt good before, i could eat and drink anything and now i just have that needing of belch all the time (and i can't) that is dirving me crazy. I already visited a psychiatrist and it is not anxiety. Can you help me?

Regards,
Jose
