Les, lex reflex esophagitis grade A.

I am an athlete and suddenly fell ill on last December. My doctor was very quick to diagnose my problem, i was suffering from B12 deficiency and Les lex reflex esophagitis grade A. I took esogress D for 2 months and changed my life cycle. But my symptoms also changed now. I was getting vomiting sensation and vomit only gas frequently along with Dry mouth and cough. I was not able to lift heavy weight things or play aggressively. If I do I was getting empty vomit. Now I can play and lift. I don't get vomit sensation like earlier. I can do all the activities Only thing that is bothering me is burning sensation. Sometimes it's heartburn and sometimes stomach burn. It won't disturb my sleep but if I sit I get this along with light cough. If I get involved in sports I don't feel this. . Should I go for another  endoscopy or scanning ? Or continue esogress D or other medicine ?
