Since I last posted I've been feeling much better, but now have very new and strange symptoms. I've been seeing flashes in my vision, felt like I was misreading text or having difficulty expressing myself verbally (words came a bit more slowly than usual), and went to the ER when I saw (and a friend confirmed) my
. I've also had a recurring,
of tiny red dots that is only ever present on my right hand, and comes and goes rather quickly. All symptoms started two or three weeks ago. I can't see a doctor for a week or two, but when I can, what kind should I see and what should I ask about?
When I was in the ER they tested my intraocular pressure with a tonometer
and that was totally normal. The attendant doctor did not
observe and problems with my pupils. An eye exam (non-dialated) didn't turn anything up. A CT scan was done as a precaution and (to my great relief) no abnormalities were found.
The flashes of light started occurring in my peripheral vision, and in those cases it's not really like I'm seeing anything so much as I visually detect movement out of the corner of my eye (turning my head, I see nothing. Since this started I've become hyperaware of my peripheral vision and occasionally experience what I think is a "flash" only to see it was a glint of sunlight off a car's hood or some other normal cause). I also see dots in my central visual field that are usually pinprick sized and stationary, lasting only a few moments, an experience not unlike seeing the cue dots
in film. Occasionally these very tiny, bright, dots will meander about for a few moments (maybe a second at most) and then disappear. The largest "dots" subtend a portion of my visual field about as large as my thumb from knuckle to finger nail held at arm's length (these rarely move, but last slight longer than others). These are not
afterimages... they seem to occur spontaneously in environments without obvious sources of concentrated light.
As far as the language use symptoms go, I feel like I make many more mistakes than usual reading - typical examples would be combining letters or sounds from two adjacent words and detecting a nonexistent one for a moment, or skipping over words entirely and having to backtrack when a sentence stops making sense grammatically. I find it's taking me longer to read in general. Likewise, I'm usually a pretty easygoing conversationalist and rarely have trouble expressing myself, but lately I've had bouts where words come with difficulty or I have to pay particular attention to form sentences. I ask people to repeat themselves fairly often.
All of these symptoms are episodic, seeming to occur for a few hours at a time, with no obvious pattern save that I generally feel better at night.
No real headaches outside a very dull ache every now and then. A bit fatigued. No fever or anything.
I'm going to see an ophthalmologist in a few weeks, and a neurologist after that, but in the mean time I'd like to figure out some likely causes of these symptoms.
