Hi.
Yes I've had them. Ive always suffered from migraines, but the ones with a banging headache, then a couple years ago started having auras, they usually come in the shape of wiggly lines and flashing lights, always in my right eye. The headache isn't that bad, but it all knocks you about a bit.
I think it's normal to have them last up to about 30 mins or so, and then they go, but sometimes I've had them return after 15 minutes or so, again.
I feel sick with mine too.
Could be stress related, and hormonal too.
I did worry at first, as like I said, I've only ever had the real, painful migraines.
Just try to relax when they occur again, and hopefully, they'll go for good. xx
