Brief Answer:
Acid peptic disorder.

Detailed Answer:

Hi,

I would come up with two possibilities, these include.
The first possibility is of Peptic ulcer disease or Hiatal hernia. Diagnosis can be confirmed by upper GI endoscopy. Try raising the head of your bed about four inches with blocks. It also might help to avoid eating or drinking for two hours before you lie down.She may need drugs like proton pump inhibitors.

The second possibility is of pancreatitis Pancreatic enzymes like serum amylase and lipase should be measured to rule out any pancreatic cause.
I suggest you to consult a physician and get an ultrasound upper left abdomen, pancreatic enzymes, upper GI endoscopy to rule out any peptic ulcers and a chest x-ray done.
