I have a lot of pain in my neck and lungs when I breathe in deeply and I do smoke. It's so bad that I can hardly breathe. Another problem I have is I have been randomly choking, not on food... which is strange but I just choke... maybe on an air bubble? Are my symptoms related? I also have endometriosis and had surgery about 7 months ago, now my pain is back and worse... I'm on birth control but I am still lightly bleeding and having clots come out... What's WRONG WITH ME? 19, female

Get yourself to the hospital NOW. This could be something as simple as pneumonia or as complicated as a pulmonary embolis.

I have an appointment set up for the 12th, should I just go to the hospital like you say or wait for the appointment? I don't feel like I'm in any medical emergency... only when my symptoms happen which is about every other day or so.
