for the past 5 days I have had shortness of breath- I feel like I kind of drowning or suffocating, like I cant get enough air. I went to the ER last night and after a blood test to check for clotting and a chest xray they couldn't find anything. They had me use a Nebulizer and sent me home with an inhaler assuming it was allergies ( I have never had allergies, these symptoms, or asthma, nor do I have a family history) The nebulizer only worked a little and for a short amount of time, the inhaler hardly works. I have no excess phlegm, no rattling, no coughing, no pain. I am a 19 year old female who does not smoke ciggarettes, smokes marijuana occasionally, no other drugs, never drink. I am active, and have a good weight for my height, no medications, no birth control. I am pretty freaked out about this, expecially because I don't have insurance and last night probably cost me a a handful of hundreds that I can't afford.
