Thanks for writing your query.
Pain in the region described by you can be due to some inflammation in the intestines.
You can take antacid
150mg along with antispasmodic containing Dicycloverine
twice a day after meals.
Take precautions in your diet. Eat light meals with less spice and oil, prepared in hygeinic conditions.
Get yourself examined by your doctor to rule out appendicitis
. Take medicines under medical supervision only.
You can get your stool examined to know if some amoebic or bacterial infection is present.
I hope this is helpful to you.
