Yesterday I had shimmery patches in my field of vision, and an overall lack of focus. It lasted about 3 hours and was followed by a headache (not severe), nausea and tiredness. I had had the shimmery vision before, a few months ago, for about 25 minutes, with no other symptoms.
I was fine this morning but the same thing happened again this evening, with a worse headache.
I have immediate family members who suffer from migraine but it's more painful than this and doesn't involve vision problems.
Do I need to see someone about it? We're going on holidays on monday for 5 days.
