The conversation between human and AI assistant.
[|Human|] my daughter is 15, she has been having chest pain. also a headache and nausea or stomach pain before or after the chest pain. she says her heart feels like it is pumping air or hollow. Sometimes it feels like it is pressing on her breastbone. also had some lightheadedness or passing out feeling.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Possibility of stress related symptoms is more. But better to rule out heart diseases because of left sided chest complaints. So get done ECG and 2d echo. If both are normal then no need to worry about heart diseases. Stress related gastritis can cause chest pain, nausea, chest tightness, pressure etc. So consult psychiatrist and get done counselling sessions. Try to identify stressor in her life and start working on its solution. She may need anxiolytic Chat Doctor.  Ask her to avoid stress and tension. For gastritis, give proton pump inhibitors and prokinetic
