I think you are having gastric problem, there might be evident reflux of gastric contents from the stomach or micro-reflux, which is not noticeable. I would advice you to drink plenty of warm water, throat gargles with povidone iodine
mouth gargles, 3-4 times/day after food and also you can take proton pump
inhibitors and a prokinetic drugs after consulting your doctor. Avoid stress
, oily food, coffee, tea, alcohol or smoking
if any. Eat plenty of fresh fruits and vegetables.
