I have a gurgling bubbling sensation under my ribs . Usually on the left side, but It does come and go and it moves to the middle and right side too. The bubbling lasts for about thirty seconds and occurs probably every 3 minutes. And yes it is painful when the bubbling occurs.
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of HERD (gastroesophageal reflux disease) is more. But better to get done ECG and 2d echo first, to rule out cardiac diseases. If both are normal then no need to worry about heart diseases. HERD can cause gaseous distention and bubbling feeling. It is due to laxity of gastroesophageal sphincter. So follow these steps for better symptomatic relief. 1.  Avoid stress and tension. 2. Avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals. 3. Start proton pump inhibitors and prokinetic Chat Doctor.  4. Go for walk after meals. Quit smoking and alcohol if you have these habits. 5. Lose weight if you are obese. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
