Sometimes I do, sometimes I don't . The vision disturbances is one of the more common precursors that I get. Sometimes if I get my medication quickly, it doesn't progress beyond it.
When I first had my migraines, over 40 years ago now, people around me thought I was having a stroke and I was often taken to hospital.
Some of my other signs are slurred speech, loss of use of an arm or hand, numbness and tingling in the face, so you can see how like the symptoms of a stroke it can be.
The vision disturbances are similar to those I got when first going very low carb and virtually seeing the sugar leave my eyes. Very odd, but only temporary.
