Thank you Karen, for the information,
If you feel increasing difficulty in breathing, then you need to call 911 or go to ER.
As the spasm is subsiding & the breathing is easier in last 2 nights, then you can wait for endoscopy in 10 days.
Your oxygen saturation is also good.
You are right that consulting ENT doctor is also an option.
But GI doctor can look for reflux too.
I hope he will be able to diagnose it.
I will be happy to assist, if you need any further clarification.
