Had the feeling of a lump when swallowing for 3days with a need to burp. today burps have food particles in them 3 hours after eating. is this gerd?

Probably: This type of symptom occurs with reflux, hiatal hernia,esophageal obstruction or motility disorder. A gastroenterologist is best qualified to evaluate and advise you for this symptom. In the meantime avoid fatty foods as they delay stomach emptying. Eat smaller feedings several times a day instead of large meals. Don't eat late at night and sleep with your chest higher than your abdomen.
