Dr. I am suffering from stomach pain(just above the stomach and below chest) since last 3yrs. I have done endoscopy but nothing found wrong, gastrointestinal endoscopist says that your digestive system is weak, so you are suffering from this type of pain, according to his advise I have taken alopathy treatment for about 1yr. but no improvement. From this treatment I aditionally suffer from acidity and insomnia. Can you suggest me best ayurvedic treatment for this pain?
