### input:
I am a 20 y.o. female. I weigh 114 lbs and am 5 foot 3 inches. I have had chest pain now consistently for about 12 hours. Well, I wouldn t exactly call it pain, but definitely severe pressure with intermittent pain. It does seem to have gotten a little better since it started, but earlier today I was very short of breath and it felt like there was air or something in my lower throat. It also felt like something was pushing against my trachea. I have been slightly tachycardic and my BP was 139/92. I can also feel pressure, maybe almost tingling in my upper left back muscle, like it s been pulled or something. I m worried because I know unrelieved chest pain is a problem. I m also worried because I ve been on Adderall XR 40mg for about 4 years now, and I know there are a lot of heart conditions associated with that. I plan on going to the Dr. tomorrow morning if it hasn t subsided but I m honestly a little worried to go to sleep if it s something more serious.

### output:

Hi dear though you are just 20 but as you are on amphetamines for 4 years a probable cardiac causes to be ruled out, amphetamines can cause ischemia, cardiac ischemia(less blood supply) is a very common side effect of using amphetaminesThey can also cause lung condition like pneumothorax which also presents with the same symptoms amphetamines can also cause severe gastritis and heart burn which also can present with the same symptoms would suggest you to go forEcg2d echo chest X-ray PA view this will help you to reach a diagnosis that what is the exact cause of pain and medication can be taken according to diagnosis thanks
