<s>[INST] Hi been having tightness and shortness of breath, I have to yawn at times to catch my breath. Also having flattery feelings in chest. The tightness gets worst after I eat. I feel better when I lay down. My chest gets real flattery when I get mad and upset. [/INST] Hi welcome to the Chat Doctor If anxiety, stress history associated then it can lead fast heart beat or palpitations as reflex mechanism.... If you are having gastritis or ulcer in stomach pantoprazole can be prescribed for that... (stress can lead ulcer as well...) I am thinking on stress direction as in history it is written as you are having some mood problem... Still before labelling it as stress related check your blood pressure and investigate with EKG also Take care Hope your concern solved Consult physician for examination </s>
