@hellomiakoda Oh, I always get those as well! I've always described it kind of like twinkles just at the edge of my peripheral vision, but your description is better. I don't recognise auras though. Although I do experience difficulty focusing on things like text, it just won't be as sharp as it normally can be and the more I try the more unpleasant I'll feel.
If I manage to quickly find myself an Ibuprofen or equivalent and go to bed when I still have those symptoms but before it escalates to an actual migraine I usually avoid the majority of it. I'll still feel a bit drowsy and worn down for 6-24 hours afterwards though. Can you also dodge the worst of it in any way?
