I also took some medication and it got rid of the problem and it has never returned. Every so often I need some Tums, but nothing like before.
I hope the doctor gave you and your daughter some diet advice like avoid spicy foods, really fatty foods, etc. I hope this is not an unwanted suggestion, but you might consider taking your daughter to an acupuncturist or Chinese herbalist to discuss diet and perhaps some herbal formulas. I know people are often skeptical, but this medicine has been practiced for thousands of years and can really help get to the root of many issues.
