I Was Seen In The E.r. For Possible Brain Aneurism.

I was seen in the e.r. for possible brain aneurism. The C.T. showed no abnormalities. However, it has happened 2 other times in the past 6 months and dropped me to my knees. this time ive had it for 4 days. I feel like my head is in a vise with direct pressure on the top of my head and my left ear tends to bleed when this happens.
