They won't send you home with anything - they are not your docs - you have to get to your doc and get something now. The ER docs are just for emergency, not regular care.
they did a migraine protocal while i was there which consisted of nubain,benedryl and an ant nauseous med thru i.v.! but no they did not send me home with anything so i'm pretty scared of it starting again.
Did you get anything for pain relief?
That is classic migraine though, pain on one side, wanting to throw up, effecting the eye, etc. but I hope they checked you out.
well i went to the hospital and they claimed i was having a migrain on one side of my head. stupid. they did say my cyst was probably hitting a nerve.
Seek medical attention - any sudden changes would mean that you need to see a doctor.
