pain
"I was recently diagnosed with silent migraines. 10 minutes after a light stimulant EEG... I was walking into walls and felt drunk but without the fun part. 
I was told not to go to the ER. I called my PCP and finally he said to go after the "silence" of the migraine turned very ugly and painful. After being administered Valium, Zofran, and Vicodin... nothing. Finally, Dilaudid was administered along with Phenergan. I was out of my make-shift mask, turned the lights back on, and tolerated noise within an hour. I was out of bed and ready to leave. 
I went in thinking I was having an aneurysm and left a completely different person! Highly recommend for severe migraines."
