<s>[INST] Im 22, 5,9 , and Have GERD, and have extreme heart pain. At night I cannot sleep due to heart palpitations. In the morning I feel really tired, out of breath just walking up the stairs, and pain across the back , on the left side. The area over my heart is really tender, and I have frequent heart pain all day. I also feel like I cannot breathe in all the way. I went to the docters, but they say my EKG is fine/ Blood pressure is normal. I feel something else may be wrong but they are not seeing it. Im told Im fine and too young to have a heart problem. [/INST] do u consume drugs or smoke.These can cause heart problems even in young age. But even acidity problems can also lead to similar symptoms that of heart disease. so first you be proper medicine for gerd like pantoprazole 40 mg beforebreakfast, syrup sucralfate, avoid spicy, heavy meals.if You are still concerned then you can get one stress test done which can rule out heart disease. </s>
