Small hiatus hernia over acidity. Time!

Hi last year I was detected with small hiatus hernia , due to which I do not feel hungry, always feeling full, indigestion, constipation, vomiting anytime, nausea, over acidity in heart and stomach area it's feel like burning sensation in my heart and stomach due to which I sometimes feel burning sensation in my left hand , I visited 2-3 gastroenterologist they all are saying nothing to wry it's completely normal but I am not feeling happy feeling always uneasy in my chest, since last 10 days I am on medicines but till the time I take medicine m fine and if miss one dose too then I feel burning sensation over and do vomit one mouth at a time, I have a migraine too sometime when my migraine triggers I do vomiting that time too , but right now my main concern is to cure small hiatus hernia symptoms of burning sensation in my stomach and heart , and the indigestion part too of doing vomiting one mouth at a time
