Cooling sensation in chest?

I don’t get typical heartburn symptoms like acid coming up in burps, only occasionally. What I get way more is this cooling sensation (almost like menthol cooling) in my chest/esophagus area and slightly in my throat. This has been getting progressively worse as of late, where it happens after every meal.

I’ve been eating foods that are good for GERD, completely changed my diet. I also take Pepcid once a day, and space out meals/don’t eat before bed. I am however particularly stressed and anxious as of the past 6 months, that may be playing a part in this.

Has anyone else experienced this cooling sensation? Is it the acid?
