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.
