Hi @collage, According to an article I found, "Acid reflux is associated with a hiatal hernia and can cause heartburn or regurgitation. Excess belching or upper abdominal and lower chest pressure or pain can also occur. Prolonged and frequent reflux of acid into the esophagus may cause damage to the esophagus resulting in ulceration and bleeding. Scarring and narrowing of the esophagus can also occur with chronic reflux and cause difficult or painful swallowing. Other symptoms of gastroesophageal reflux can include sore throat, hoarseness, excess salivation, the sensation of a lump in the throat (globus), sinusitis, frequent throat clearing, cough, wheezing or asthma." https://www.idahogastro.com/hiatal-hernia/
Are you currently having any chest pain or coughing associated with your symptoms?
