My son has been saying that he's having chest pains for the past two weeks. I thought it might just be gas passing through his chest so I have him some gas meds. He burped, but two days later and for the reminder of last week he has continue to say once a day his chest hurt and with trouble breathing. When I asked him if he has trouble breathing the hold time he said no more like it feels like pressure on his chest. Also he said drinking water seems to help. Any ideas what this could be?
