Suggest Treatment For Polyps In The Abdomen With Severe Pain

My daughter has been to 4 different towns for some terrible pain she is having in the upper part of her stomach. She has had an ultra sound on her gallbladder and also I test with dye to check her gallbladder. She has had an upper GI. She spent 5 days in a hospital to no avail. She has polyps in her stomach and the bottom of her esophagus. They came back not cancerous. She lays and cries and asks why can t they find out what is wrong with me. Why do I have to feel this way. Just want to know if you can give me an idea of what we can do next.
