Any doctor's out there, medical answer needed!!!? I am a 26 year old male. I had an episode 10 days ago where I lost consciousness and had difficulty breathing, 911 was call and by the time the paramedics arrived I had come to.  I developed a severe pain in my head/back of neck (not from falling when I “fainted”) that has persisted since then.  I was taken to the emergency room and when doctors could not conclude what was wrong, and that my symptoms were not life threatening they sent me home.  Thursday it happened again.  They did a cat scan, spinal tap, EKG, EEG and blood work – all inconclusive.  They sent me home and told me to make an appointment with a neurologist.  I have developed a new symptom.  I have a radiating, throbbing pain in the left side of my chest which IS NOT traveling down my arm.  I have not lifted anything heavy.  The closest hospital’s ER has a long wait and would not provide me with any ideas over the phone.  While the pain is bearable it is frightening because of the timeline in which it occurred.

Summarized question: Are loss of consciousness followed by severe back of neck and head pain and a radiating, throbbing pain in the left side of the chest that does not radiate down the arm related symptoms?
