Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of either
esophageal motility disorder or GERD (
gastroesophageal reflux disease) is more.
In both these conditions, patient is having symptoms in lying down position and while eating.
So better to
consult gastroenterologist and get done upper GI scopy.
Start
proton pump inhibitors and prokinetic drugs.
Avoid stress and tension.
Avoid hot and spicy food. Avoid junk food.
Avoid large meals, instead take frequent small meals.
Keep 2-3 pillows under head in the bed to prevent reflux.
Quit
smoking and alcohol if you have these habits.
Don't worry, you will be alright.
Hope I have solved your query.
I will be happy to help you further. Wish you good health. Thanks.
