Ultrasound scan was normal, liver test kidney test all normal. But still she says pain near middle of rib bone. We even took ECG it's normal. But for past 3 years the pain come and go when she eat spicy food. Ex pepper added food, Many doctors suggesting to take endoscopy. To check inside the stomach. But she was refusing. For past 3 months she got white and black layer in her mouth. She can't even take little spicy. Only liquid food or curd rice she was taking. I'm little bit worried other than endoscopy what we can do to make her eat the food she likes. Atleast not with more chilli. Please help me to diagnose the problem.
