Hi There, I'm A Bit Poorly With A Cold/cough. I

Hi there, I'm a bit poorly with a cold/cough. I have had headaches, but for some reason I have stars, or flashing lights in my vision. Similar to an aurora you get with a migraine but Iv had that before and usually it's much worse, then goes after about half an hours. These stars are less prominent in my vision but have been on and off all day.
Is that normal?

Thank you.
