Hi! Good evening. I am Dr Shareef answering your query. Yes, these symptoms could be due to your diagnosed hiatal hernia. However, chances of an amebiasis would have to be ruled out specially if you were used to eat from outside. If I were your doctor, I would advise you for the following: 1) A routine stool test for ova and cyst and treat it if positive which would relieve your symptoms. 2) Elevate the head end of the bed with two blocks on each side, so that the regurgitation does not occur while lying down, and the contents of esophagus and stomach flow down with gravity. 3) Some modification in your diet like more of roughage, enough liquids, avoidance of oily, fried, and fast food along with avoiding any kind of alcoholic beverages and smoking if you do. 4) Regular routine exercises like morning walk depending on your medical fitness. 5) Prescription for a prokinetic agent and a proton pump inhibitor for symptomatic relief and to have a control on the acid production and facilitate movement of gastric contents downwards 6) Your fever could be due to any kind of intestinal infections specially if you eat from outside, or might be an independent entity itself which would have to be investigated. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef
