I Had Surgery Back In June 28,massive Hiatus Hernia. Had

I had surgery back in June 28,massive hiatus hernia. Had to pull stomach and part of colon back down in normal position. Ever since I have had severe reflux and also through up my food everyday. Have also developed a bad cough with clear congestion I spit. Currently my dr. has set up an upper gi next week to find out the problem, I just don't have much faith in her any more. She is a general surgeon, bariatric surgeon. Your opinion please
