question: I'm just wondering the worst case scenerio until i get to a doctor in person. I believe i have a bacterial infection in my lungs. When i try to take deep breaths or just even breathing i get a sharp pain throughout my left shoulder blade, sometimes switching to both and up my neck, causing a headache as well. When i move around such as to a different position to sleep in my heart beats fast and i can feel my lungs ache, almost like they can colapse at any given time. I can't sleep because of the pain. I'm only 19, and i do smoke. I've smoked for about 5 years.
