Swallowing difficulty. Sleep in night.

I have a acidity from past several years and from 2 years I have throat problem difficulty swallowing.both liquid and solid food. When ever I eat or drink anything some sticky mucus is generating in my throat which I can not swallow..did endoscopy 2 times .one doctor said antral gastritis and GERD Another doctor said antral gastritis.i took ayurvedic medicine which solved burning sensation and gas almost.now only the problem is mucus in throat and some time I will get difficulty breathing due to acidity problem . can't eat or drink anything and I can't sleep in night.. please suggest me what could be the disease or cause of this problem with proper solution Consulted many doctors personally.did not get good results so posting here. Doctors telling endoscopy pipe is going so food will also go there is no problem.but I am facing lot of problem while swallowing food and water
