### input:
My daughter 14 and has been having really painful chest pains for a while now. she used to have acid reflux, we went to the doctor and they gave her medicine for it and it went. but a couple months on from then shes been getting a different pain on the left side of her chest, by her heart. it feels really tight and its hard to breath. but she takes gavisgon and it goes. she gets woken up, mostly every night now, at about 2/3 in the morning. and sometimes get it in the evenings when lying down, or even just slouching in a chair. also, our family has history of twisted organs (dont know the medical term), my father had twisted lungs. is there something wrong with her, or nothing to worry about? thanks

### output:

Thanks for your question on Chat Doctor. I can understand your concern. Possibility of HERD (gastroesophageal reflux disease) is more likely for her symptoms. GERD is due to laxity of gastroesophageal sphincter. Because of this, the acid of the stomach tends to come up in the esophagus and cause chest pain, chest tightness, breathing difficulty etc. So better to consult gastroenterologist and get done upper GI (gastrointestinal) copy. Hiatus hernia should also be rule out. Treatment of HERD is lifestyle modifications as following. Avoid oily and spicy food. Avoid large meals, instead take frequent small meals. Avoid stress and tension, be relaxed and calm. Take pantoprazole tablet on empty stomach. Keep 2-3 pillows under head in bed to prevent reflux. Go for walking after meals. Don't, she will be alright with these lifestyle modifications. Hope I have solved your query. I will be happy to help you further. Wishing good health to your daughter. Thanks.
