Hi,
The pain you are referring to be worst when lying down could be related to:
- stomach problems (reflux-
GERD,
gastritis)
You are having
back pain also due to the same nerves passing to the stomach and lower back.
I'd advise to:
- avoid spicy, chillies, fried, fatty foods
- avoid carbonated, coffee, alcoholic drinks
- eat often and small portions,
- do not lay down immediately after eating
- do use 2 pillows when sleeping
- apply warm clothing to the stomach and back area and to your feet
- start taking otc antiacids and the medications as prescribed by your doctor.
All the best!
