Welcome in H.C.M.
I read your query carefully and after co-relating all facts it appears as you are having LPR (laryngopharyngeal reflux disease
This is particularly associated with hyper acidity and is always felt in throat as a choking. As your endoscopy
and examination by ENT doctor favors for esophagitis
and no local pathology had been detected as neoplasm
Therefore you may take-
1- Antacid with PPI.
2- Avoid spicy food.
3- Take adequate fluid.
4- Take sound sleep at night.
This will help you.
