I've been getting these strange headaches during the past couple of weeks. Now I am no stranger to migraines, not in the least. I'm used to seeing little floating sparkles and black specks, but I've had completely different visions. What I've seen looks somewhat like a halo or an aura that is crescent shaped. It is very geometric, like the crescent has dozens of prisms that are reflecting the northern lights at different angles and brightnesses. Like I'm looking into a portal to another dimension.
Whatever I am attempting to focus on, the sparkling seems to wrap itself around it. The first time it happened, I thought maybe my eye was wigging out. So I closed it. Still saw the sparkles. So I closed the other eye. Still sparkles. So I closed both eyes. Still sparkles. Okay, not my eyes. So it's something in my head. Great. That episode lasted an hour, then followed with a headache that felt like a vice grip around my crown, but also felt like extreme pressure from the inside, like the brain is swelling with every heart beat. I've experienced one or the other, but never both at the same time. I literally thought I was dying.
A few days past, then I had another sparkle vision, this time it lasted about 2 hours, then came the headache that had me vomiting.
Well, yesterday, I WOKE UP with the sparkling crescent already on display. Not a good sign. I went into work, did the best I could despite my vision being obstructed with this bright light refracting object. After 4 hours, it wasn't showing any signs of letting up, so I told the Chiropractor that I work with what has been happening, and asked if that sounds like it could possibly be an optical nerve impingement.
He sent me to the imaging center for an MRI immediately. He called them with instructions while I was on my way. Within a half hour of leaving my office, I was in the MRI tube. Then things got fun.
So in the MRI, the machine puts out all sorts of different vibrating (screeching) sounds at different frequencies that cause different responses in your body. Well, every 5 minutes or so, the machine does 3 long sounds that sound like the emergency broadcasting warning. Well, my body reacted to those. Every time (on the 3rd buzz, which is odd), my right arm all the way from my shoulder joint down to my fingers felt like it was being zapped & electrocuted. It was very painful! I told the tech afterwards, and he said he'd never heard about that before. I really wonder if it's connected.
So here's my questions:
First, has anybody had any headache/vision issues like that? If so, did you ever find out what it was? Is there something that triggers it? Is it treatable? Am I doomed for the rest of my life to have it conjure itself up at the most inopportune times?
Second, has anybody had an MRI that their body reacted to like that? Am I abnormal?
