I have gone through your query.
From your history and symptoms it is most likely Gastro-esophageal reflux disease. Acid from the stomach goes back to esophagus
causing heart burn and nausea
Prilosac contains omeprazole
which reduces acid production in stomach, so your heart burn diminished. To reduce the reflux you need to add domperidone
to your prescription. There can be chance of H. pylori infection and it can be ruled out by tests. Consult your treating doctor with these options too.
Hope I have answered you. You can close the discussion and rate the answer, if you don't have further query.
