GERDS can definitely cause you to reflux and aspirate. You need your esophagus scoped. You need to know if you have a stricture which is scarring in your esophagus caused by acidic reflux which can cause food to get stuck causing and accumulation of saliva which if you're not careful can cause you to aspirate as well. It does go down eventually. Also, you need to know if your lower esophageal sphincter (LES) is wide open or is it closing properly. I had a LINX band placed and a failed Nissan reversed back in 2019. Esophageal spasms are also a real thing. That causes food and liquids to get stuck as well. For me, that was caused by stress. Depending on how long you've had this problem the Doctor should also check for Barrets esophagus which can be precancerous.
Do your own research. You absolutely MUST be your own advocate. Never ever be a passive patient.
