Having a tight feeling while swollowing.

Dear sir / madam. I am having a tight feeling while eating and swollowing and sometimes when I ate , I had the some food particles comming out back to my mouth ... I don't have abdomen pain . My bowel movements are very normal .. but I am having severe nausea every time no matter what I get very nauseatic .vommiting sensation is there all the time along with it ... my apitite had lowered considerably , still could eat well once food been served .. I consulted doctors they gave me mucaine gel and raso l tablet ... few days back I had a sharp pain in the diaphragm now it's gone . But I feel acidic but not stomach pain ...I do get prolonged dry cough but not a consistent cough just a roll of cough .. I am perplexed that this couldn't be addressed by health professionals near my vicinity . When i check google typing the symptoms it directly shows esophagus cancer. I just couldn't take it anymore. Please any health professional please try to help me out very genuine request ... thanking you
