About 10 months ago I started to feel mild intermittent nausea
, especially at wake up time; nausea typically subsides after eating/drinking. Few weeks later, other on and off symptoms started appearing: stomach churning, burping, incontinence, burning in esophagus. All of these symptoms, along with nausea, were intermittent with some days worse than others. GI doctor performed stool tests, blood work, sigmoidoscopy, endoscopy, however everything came out normal or as expected.
