today, i had a severe pain on the left side of my chest. like in my left breast, extending towards the side and back. it's constant pain and i feel like vomiting a bit because of that pain. it got so severe that i had to lie down and then it felt a bit better but it's still throbbing. i recently got put on antibiotics (azithromycin) for a throat infection, but these pains are not a side effect. i have experienced the side effects of my antibiotics; i had diarrhea and slight stomach pains, but that was it.
i'm 16; female. i know i'm very young but i'm still scared if this is something serious. thanks so much!!!!!!!!
