Was the pain one sided with pulsating quality?
How long did this headache last both times?

I can't recall the first time it happened whether it was on one side or the other... but I remember that I was in pain until I went to sleep that night.
Saturday, it was mainly my right eye that was hurting after the vision came back.
The blurriness lasted about an hour and the headache put me on the couch for a couple of hours. It wasn't pulsating (that I remember), it felt like sharp pain.

I do get headaches just about every day, which do pulsate (I can feel it with my fingers), but they aren't bad enough for me to take any kind of pain reliever.

You may want to have a X rays or CAT from your cervical vertebrae. Sometimes there are compression of the nerves or arteries that goes through the spine. This can cause dizziness, problems with eyes or headaches. There are other possibilities, this is just one of them.

Well, yesterday (Monday), I had a persistent headache all day. The pain was in my temples and brow bone area.
I went to sleep around 9:30 and woke up at 6am today. My headache was back this morning. This time it is only on the left side of my head, in my temple and left part of my brow bone.

Before when I would get the vision loss, I could feel it coming on because my eyeballs felt numb.
Today, my left eye is numb. I'm scared it's going to happen again.
What I'm really scared of is something awful is wrong with my head.

I have health insurance but I do not have a regular doctor. I am short on money. My health insurance is not very good, it doesn't cover much.

Edit: I just wanted to note that my problem isn't exactly "blurred" vision... It's a loss of vision. Every part of my vision area is black except the very middle part. I made "Os" with my hands and put them on my eyes to block the surrounding vision areas and I could see better.
When it happened Saturday, I was sitting on the couch and my daughter was playing on the floor, looking right at me and I couldn't even tell if her eyes were open. It just looked black where her eyes were.

Well, That sounds like an increased pressure of the eyes. You may want to visit an ophtalmologist to check your eye's pressure. "tunnel vision" is a condition when the person is developing glaucoma, a condition where the inside pressure in the eyes is increased. Due to your age, I would doubt that is glaucoma, but you better check this first.

Ok well I went to the hospital early Wednesday morning (November 5).
They gave me a CT scan of my brain.
I left the hospital around 630am.
3 hours later, the ER doctor called me at home and wanted me to come back.
He said he thought he saw something peculiar on my CT scan, in the area of my pituitary gland. Possibly that a tumor or aneurysm was pushing on where my optical nerves criss-cross.
SO, I went back to the ER. The neurologist on site said he did not think it was anything in my head, that it was likely my eyes that were the problem. So he sent me to the eye institute. The doctors over there ruled out anything related to my eyes.
SO, I have no idea what the problem is at this point.
My regular doctor has set me up to have 2 MRI's done on my brain-one with contrast, the other without, on Wednesday.
Updates to follow.

Ok,
If the neurologist said it wasn't anything wrong, that's good news. You may want a second opinion with your CAT's with anoter neurologist if you want.
Hope your MRI will be ok too,
I suggest that you visit a retina specialist.

God bless you

Thank you.
When the neurologist sent me to the eye center, they checked everything and said my eyes and retinas are perfectly healthy.

I am feeling the exact same thing. It's frekaing me out reading this.

I haev the exact same symptoms and my head is KILLING me. I don't know what to do. I should go for a CT Scan I guess...

FREAKING OUT probably isn't a good option, huh?

It's very interesting reading everyone's experiences with "blurred vision". Out of nowhere, a few days ago, all of a sudden my vision got blurry working on my laptop. Didn't improve so I went to my eye care specialist, who said all was fine with my prescriptions for reading & the PC, but that my distance prescription was worse. Nothing has improved in a week & I am still having sporadic trouble reading books & working on the laptop. It's all very frustrating & scary. I'm the type who reads at least a book a day, for my whole adult life. And who works online a lot too! Can't figure out what I've been doing different to bring this on, but it's all very sudden & alarming. Time for the doctors to check me out I guess also.

i am 27 male, when i was 16 i remember driving down the road and all of a sudden my vision started going out, I could see out of the right corner of both of my eyes, i couldn't see the yellow line but i could see the white line as long as my eyes were striat i could see the white line out of the corner of my eyes. i thought i was going blind at first. i then had a really bad headache that put me down to were i didn't wanna get outta bed when i got home. i usually have the headache for about a week after my vision comes back after about an hour or so, during the headache i can't turn my head normally or anything without my head having very very sharp pains shooting thru my eyes and head, all over my head, i have had the right side of my body and face go numb burning sensations and didnt wanna move at all.i had a mri done and nothing there, my backbone was checked but nothing, i got tired of all of the headaches and started going on and when i do get a headache i try to keep going even if im throwing up or anything. i have been putting up with this for 11 yrs now and no one can find anything that is causing them. I have hypertension blood pressure as well, some drs. have told me that my headaches could be caused by my high bp. then some drs; have told me that some food and smells could be causing them. im a painter and the dr even told me that even the paint could be causing them. well my job put me off painting for a while and i still got the headaches. i dunno what to do anymore. i just gave up on it.if anyone has got any info on this then it would be appreciated. i would love for this to go away. thank you so much.

I am no expert, but I do get similar symptoms during my third trimester of pregnancy. My vision blurs to the point I can't read a computer screen, followed by numbing in my arm or hand (usually only on one side- at the moment it is my left side), then the painful migraine sets in and the epicenter of that can vary (sometimes in front by the eyebrows, sometimes at the base of the skull). If it is comforting to anyone, I feel that my migraines are completely hormonal in nature because I only get them when I am pregnant- and late in pregnancy. But I get them a lot then. I am taking the time to post this, so that you can maybe have some comfort that it your symptoms may be due to some hormonal fluctuations your body and not a tumor, etc.

Best of luck to you!
