Lightning Flash Across Eye

Hi guys.

Earlier today whilst out walking the dog I had a bright white flash across my eyes, as if I was standing under lightning in the sky. It seemed to be two quick bolts, possibly the same one but it didn't seem to come from there.

I've been having a pretty rubbish day and felt edgy all day. Light headed, palps, shaky. Your usual anxiety symptoms! But I just felt anxious at the time, no headache etc

I saw a neurologist last week and had a full work up (no CT etc as they were not deemed necessary) and falls were put down to my my depression/anxiety and my headaches were tension headaches.

Does anyone else get these flashes or had them? Really disconcerting?

I'm half tempted to run up to the walk in centre but I know that's silly.
