Hi. Thanks for your query. Noted the history and understood your concerns. Since you are a nurse, it should have been easy for you to have a proper possible diagnosis and to take an opinion of a Doctor or a Gastroenterologist. Well, heartburn is suggestive of GERD and pain in the upper abdomen also may be due to acidity related things. You can try the following: Get a PPI like Omeprazole. Take antacids when on empty stomach. Domperidone for regulation of motility and not allowing the stomach contents to reflux into the esophagus to avoid heartburn. Get an ultrasonography of the whole abdomen to get the exact cause of the swelling whether related to the gall bladder or liver and get further tests of blood for CBC, liver and other functions. Upper GI endoscopy will help to clear the diagnosis further. IF you still do not get a complete relief, it is better to take an opinion of your Doctor and get a reference for a Gastroenterologist for clinical evaluation, further investigations and a proper management. Control of stress and anxiety is very important as it is a part of the lifestyle and your job profile.
