Flickering light in left eyr

[Becky11]

Hi everyone,

I've been migraine free for 5 weeks and then had 3 one after the other. Last Monday I had one with a funny aura and since then on occasion I think I see a tiny circle, white background with pink zig zag thick lines in it which tend to flicker at the same rate as my heart. It's really unnerving again. Just wondered if anybody else had had anything similar. Please help if you can..... thank you x
