Can gastritis cause pain under the ribcage and back?
GERD or gastritis likely.
Based on your symptoms, I think you might be suffering from Gastroesophageal reflux disease (GERD).
In this condition stomach contents (food or liquid) leak backwards from the stomach into the oesophagus (the tube from the mouth to the stomach) causing irritation of the oesophagus, heartburn, watery feeling in the mouth and other symptoms.
You will need proton pump inhibitors for a week or two.
Omeprazole is usually available over the counter and can be taken once a day before breakfast. Check with your pharmacist about its availability.
In addition, you also need some strict life style modification like-
Avoid hot and spicy foods and beverages - they worsen symptoms.
If you smoke, stop smoking. Lose weight if needed.
Eat small but frequent meals at regular intervals. Avoid lying down immediately after a meal. A minimum of 2-3 hours should have elapsed after a meal.
Raise the head of your bed 6 to 8 inches by securing wood blocks under the bedposts. Just using extra pillows will not help.
Hope I have answered your query.
