I first started getting migraines at 11, they start with the aura then about 20 mins later the full on headache is there, which is pretty unpleasant. I seem to have an attack every few months.
But since I was about 17 (39 now), quite quite often, like a few times a day, I get a small dot at the center of my vision, it's normally black in colour but can be bright colours. It goes after a few minutes normally, but is sometimes persistent, and I can feel a minor headache afterwards.
Also since about 22, often after moderate exercise I'll get a large, bright, almost snowflake like light in front of my vision, and it lasts about 20 minutes.
Neither of these are as hard to read and see with as an aura is.
I wondered if they're maybe a type of "mini-migraine" and if anyone else suffers from similar things?
