HELP. "throat burping" Air stuck in throat after liquids

Hello.

I am having this very bad issue and i was hoping someone could tell me what it might be as my gastro doesnt know.

When i swallow liquid i start getting burps from my throat AS I AM SWALLOWING. Then i get many mini burps coming from my throat not my stomach.

Then i feel this pressure in my breastbone and feel something is stuck in my throat. So i breathe in deep and manage to force some air out. Then go about my day feeling air stuck in my throat.

Does anyone know what the hell can cause this? I have no heartburn.

thanks
