So, today included a trip to the hospital! whee! sometime around 8:30 this morning, I had a strange distortion in my visual field: the peripheral vision on the right side went away and was replaced by... nothingness? light? it's hard to describe. I decided that this would be an opportune time to go to the hospital. shortly after the ambulance they called got here and while I was being examined, the phenomenon went away. I was still inclined to go to the hospital and get checked out anyway, since i've never had a history of anything like that before. Their conclusion: doesn't seem like anything immediately dangerous, and it was only in the one eye, so we're going to sent you to an opthamologist. After managing to wade through all the HMO bullshit, I managed to get an appointment to the opthamologist they referred me to from the ER. Now, I await their call to confirm when I can go in.
