Is it normal/possible to have what I can only describe as an aura,but not get a migraine? I'm 53 and until my early 30s used to get a migraine about 2-3 times a year,never with an aura beforehand though. By my early 30s,I seemed to 'grow out' of them. I still get the occasional bad headache,but definitely not migraines. Yesterday,just after I had got on a bus,I noticed a strange,shimmering-zag pattern in front of my left eye. It was there even when I closed one or both eyes. This continued for about 30 minutes,getting gradually larger until I could barely see out of that eye. Then it suddenly went,vanished completely in seconds. I thought I was going to get a stonking headache,but no. Nothing. Anyone else had anything like this?
