I'm a developer and I spend a lot of time in front of my computer screen. In the last few weeks (maybe 3 or 4) I've suffered bouts of temporary blindness. It usually comes around late in my afternoon and coincides with a massive headache and sever dizziness.
Some, history here...
My mother passed away about 7 months ago from Glioblastoma. It was very sudden - she went in for surgery and never made it out. So I'm worried. Her symptoms were similar and they went ignored for 4 years or so.
So, I'm wondering if these incidents where I literally can't see my hand in front of my face is enough for me to go see a doctor. Right now, I'm subscribing it to stress. But I really have no idea.
