Hi all, I had a concussion at the end of January 2014. I noticed the static (visual) snow only in the night time. Then, in the months that followed, the snow would worsen from incidents that are jarring, like when I lightly hit my head against my headboard or when I was in a car that went over a speed bump fast. I now notice the visual snow in the daytime as well, especially in indoor poor lighting conditions. It is my most worrying PCS symptom, but I find that my head also does not respond well to too much computer use and I cannot sustain sleep.

I wish so badly for the visual snow to go away...at this point I am scared that it will just periodically get worse again and again. I hope others can share their experiences.
