I get occasional chest pain.  It helps if I drink water but the pain is scary and I feel it in my chest and up into the sides of my neck/jaw.  Sometimes it feels like someone tied a rope around my ribcage under my breasts.  Is this acid reflux or a heart attack.  I have no trouble breathing through this.
Thanks for your question on Chat Doctor. I can understand your concern. Possibility of HERD (gastroesophageal reflux disease) is more in your case because your pain is subsided after Chat Doctor.  But better to get done ECG to rule out cardiac cause. If ECG is normal than no need to worry about heart attack. HERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the symptoms of chest tightness, chest pressure, chest pain etc. So start proton pump inhibitors. Avoid stress and tension. Avoid hot and spicy food. Avoid junk food.
