I get allsorts!
Sometimes disturbed vision, wobbles, flashing lights, auras
Speech can be slurry, often nonsense, often I simply cannot say the word I need to say
Banging heads, vomiting, waves of hot and cold, very sensitive hearing or sometimes an odd sort of muffly deafness.
And sometimes I feel like I can see the back of my head, now that is weird!
I find mine are provoked by stress/overtiredness and bright lights. Also go through phases of identifying food triggers, only to find something different six months later!
sooooooooo to try and avoid them I wear sunglasses A LOT, decent ones if I am feeling sensitive, try and avoid flashy or bright lights, and I try to drink a lot of water
also I have started really attacking any headache, just in case. And tbh I am not a headachey sort of person so looking back I can see that having a bad head for a couple of days was the lead up to The Big One, so I throw all the painkillers in the house at the bad head and touchwood have not had a humdinger for a while.
