Detailed Answer:
Hi
Thanks for choosing health care magic for your query !

The problem you are facing is called Constipation.Our stomach has its own enviroment called as intestinal flora.Gut flora is the complex community of microorganisms that live in the digestive tracts of humans,The intestinal microflora is a complex ecosystem containing over 400 bacterial species. Anaerobes outnumber facultative anaerobes. The flora is sparse in the stomach and upper intestine, but luxuriant in the lower bowel.Due to old age and many other factors this flora of gut is deplished and lead to various problems with digestive system including loose stools or constipation along with pain in the gastric area.
I would suggest you to start stool softener like Lactulose 10ml once daily with half a cup of water before going to bed.This will make you stool soft.Once copnstipation is relieved you will feel much better and the pain will go away;along with lactulose start taking probiotics.

Probiotic contain a variety of live active bacteria cultures that aid in digestion. Lactobacillus acidophilus is one bacterium that aids digestion in the small intestine. Lactobacillus acidophilus also produces vitamin K, which is a fat-soluble vitamin that helps your blood clot, or coagulate. It has also been found to improve lactose digestion and reduce lactose intolerance symptoms.Another beneficial bacteria in probiotic is bifidobacterium lactis, which improves digestive comfort. Bifidobacterium lactis helps your digestion and has been shown to reduce symptoms of irritable bowel syndrome.Streptococcus thermopohilus is another beneficial bacteria in probiotic . Streptococcus thermopohilus bacteria fight lactic acid bacterium that can impede proper digestion of your food.

Advice
Lactulose once daily (as per advice of gastroenterologist)
Probiotic twice daily for 21 days
Ultra sound abdomen to rule out any pathology.

-Take two tea spoon isphagula husk with 200 to 300 mL water once while going to bed every day.
