Re: Would an Aneurysm cause this?
I think when the aneurysm gets to the point that it is unbearable, "not that any headache is really bearable," but I think with this, it means it's ruptured, and you will in no question run to the ER because of it, my last aunt that died because of this, the pain kept getting worse until it finally ruptured. A CT would typically show whether or not you have an aneurysm. I guess other possible serious causes could be a brain tumor or a stroke, however I think your in good shape if your CT was okay, an MRI would not probably hurt anything to have done though. Sometimes a CT misses things. And I hear they are more acurate with contrast dye. A cluster headache will occur to one side but it's the vision changes with it that sounds worrysome.
