Ask for a referral to an ent specialist and ask them to take a look for evidence of reflux burning.
I say this as not one day EVER in my life through two pregnancies or ever have I ever had acid reflux but I would keep waking up with such sore throats I couldn't breathe and no voice ....
It turned out that during the night the acid was burning up my throat and that was the sole reason. I'm now on a drug called lansoprazole and I've not had another one since 💕 good luck x

You might want to see an gastroenterologist. I have GERD very badly. I take deltilant every morning. I know to stay away from certain foods. It's horrible when the acid reflux comes back up.

I dont think there is really a way to tell....the signals are the same, just more active with a flare.
