You need to go to a swallow specialist. The problem is related to dysphagia. There are many possible reasons for this.
It isn't allergies.
Thank you for the advice much love!
I once had that feeling, like I'd vomit. My ENT said he saw irritation on my vocal chords and thus, thought it was acid reflux. I took Prevacid and it went away.
Now I'm weaning off of it however. Hopefully it won't return.
