So for close to a year now I've had strange head pain in the same place accompanied by a strange feeling of everything not being real. It began on a very stressful day for me, so for a while I ignored it, but it hasn't gone away. The head pain is brief, and not terrible, but persistent. A day has not gone by since last August (2011) that I haven't felt something in the right front side of my head. I went to the ER and had a CT scan (not an MRI), where they confirmed that I didn't have any large masses, which I assume would rule out a tumor (the reading came back as "normal brain scan" from the radiologist). This does not rule out an unruptured aneurysm, but everything I can find about those indicated that they're almost asymptomatic until they're about to rupture, which presumably would have already happened. The feeling that goes along with it is almost like I can't wake up, like nothing is real and my voice sounds strange to me, as do other people's. I haven't noticed any neurological impairments like numbness or drooping eyelids, just a strange feeling the is hard to describe. Nothing feels quite real, which is very disconcerting, especially since I work nights alone and I'm constantly afraid that I'm going to pass out or die or something (granted, an over-reaction, but not knowing what is wrong is freaky). The head pain is brief, kind of like an ice-pick headache, but not excruciating. It travels a little, but always stays in the right front part of my head. I would be willing to dismiss it as stress-related, but the fact that it never goes away completely and the fact that the pain is always in the same place tells me that it's something more serious than a stress headache.
Any knowledge/advice on this would be immensely appreciated. Thank you.
