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 she's been getting a different pain on the left side of her chest, by her heart. it feels really tight and it's 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 (don't know the medical term), my father had twisted lungs. is there something wrong with her, or nothing to worry about? thanks
