I feel like there's dust in my throat?

I was laying down trying to sleep and suddenly my throat started to feel a little itchy and I tried coughing to help the itch but it wouldn't help and the itchiness started getting worse and I couldn't stop coughing and had to go drink some water . Now my throat feels super dry and itchy and it feels as if I'm breathing in dust or something . What could this be ?? It made me scared that I'm having an allergic reaction or something. I don't have allergies and I don't have asthma so idk what it would be. I do have acid reflux and was having severe heartburn about 30 minutes before the itching started but I just took some Pepcid and it stopped the burning but could heartburn affect your throat? Idk what's causing this

Brandi,

Agree. ..definitely the reflux. It can cause throat irritation/coughing/breathing discomfort.

If it is an ongoing issue, talk to your doctor about a treatment plan...

...otherwise, just avoid eating late/laying down too soon after a meal.
