If started having this migraine behind my left eye about 2 weeks ago. 3 days ago it brought me to my knees vomiting and crying like a child, I could hardly stand. Went to doc, they said cluster head ache and gave me imetrix, later that day my brother took me to the er because it worsened and ct showed fluid in sinuses and they doped me up and sent me home saying sinus head ache. I have a history of head injuries and seizures and its still about the same tapering off every once in a while(only reason I'm able to type this) Other than the pain behind the eye and between eyebrows I have no other sinus symptoms. Can't get in to doc for another week and in am waiting on an approval for Neuro. Any thoughts on what this could be or tests I should ask for? Worse with movement
