I am soooooo glad that I am not alone!!(although it ***** to get these)
I have EXACTLY what you described in my right eye.
It does not take up all my vision, rather the top and outter aras of my vision.
And as you, I had I think about 3 cups of coffee, and got busy running around town, picking things up.
Mine struck me while I was out today. I actually called my boyfriend crying because it was getting so bad. I did not want to drive home like this.
I waited about 5 min, then decided that I better go before it gets worst.
I had a craving for food though, so I made lunch as soon as I got home.
At this time, it's pretty much all the way gone. It has been about 40min.
Those are ocular migraines (also called optical, visual, or painless migraines). I had no idea I was a migraineur until I got my first ocular migraine at age 42. Sometimes they are triggered by hormone changes (puberty, perimenopause) and also by specific triggers for certain people, e.g., stress, too much caffeine, too much or too little sleep (many people get them when they sleep in on weekends), weather changes, altitude, certain foods such as cheese, chocolate or wine (the food list is very long), etc.
I also panicked when I had my first one, thinking it was a stroke. The doctor reassured me it was just a migraine event. I was surprised! My whole family (mother, sister, some of my brothers, my aunt, and both my kids) all have migraine, but I'd thought I escaped--until that day I got the ocular migraine.
Migraines can also cause attacks of dizziness, hearing or vision disturbance, sensitivity to light or sound, numbness or tingling in the face or in an arm or leg, nausea and vomiting, diarrhea, trouble speaking or understanding speech, and other symptoms. You absolutely DO NOT have to have a headache in order for it to be a migraine.
If you get it while driving, I would just pull over and wait for it to pass. To avoid migraines, identify your personal triggers and avoid them. I would say that drinking a whole pot of coffee (i.e., too much caffeine) might be one of yours! It's also really helpful to go to bed and get up at the same time every day--in other words, maintain a VERY regular pattern of sleeping--and also a regular pattern of eating and other activities, to the extent you can.
Keep a food journal and see if there are particular foods that trigger your migraines.
People's visual auras can vary quite a bit. "Kaleidoscope vision" is a common description; also "flashing lights," "diamonds in a heat wave," etc. Typically they do expand and move outward/upward and then pass after 20-40 minutes, though they can last a shorter or longer time. I had three auras over several months; the third and last one was in color (the other two were just the classic C-shaped "diamond in a heat wave").
Here is an interesting video from the Mayo Clinic on migraine auras and attacks:
Lots of people have speculated on a link between MS and migraines, but I don't think there really is one, except that migraine symptoms might be mistaken for MS symptoms and vice versa (because they both involve the central nervous system). Also, hormone changes might play a role in both conditions.
You have gotten some good information here. I agree that this sounds most like an ocular migraine. As for MS, No, this is NOT how a symptom of MS show up. There is a requirement that a new symptom be present either constantly or recurringly in the smae place for at least 24 hours (some experts are now saying 48 hours) for it to be consistent with a symptoms of MS.
HOWEVER, anyone with a new onset of headache needs an evaluation - and you are no different. You should request a visit with a physician, because the NP didn't realize this needed, at least, a CT scan, if not an MRI. This is just being prudent.
I have recently suffered from very similar circumstances. Am I also suffering from just an ocular migraine, or is it something more significant? I have experienced a rollercoaster of dimensional, spinning triangles, in just my right eye. A line of them in my upper eye, and a thinner layer of them in my lower eye, and then spreading thinly throughout that eye. While at the same time, my other eye is perfectly fine. What does this mean? Fortunately this time I was home, but where will I be when it strikes me next time? Any suggestions or help out there?
I see the same thing!! It scares me so bad!!! Has anyone found a cure or treatment? I have MS so I found it interesting to see that it's related...my neuro insists it's not related...why don't they listen?
So we all seem to get it in the right eye, but its just my mind thinking its there, cause if I shut my right eye I can see it in left where right eye should be, infact I can shut both and its still there.
