Hi Patch again here,
I said before I normally only get blurred vision before a migraine or during/after a cluster headache not before the cluster starts.
Funny thing was just got back from 2 weeks holidays where I had gone approx 4 months without a cluster headache before we left. Driving in the car there the sun was in my eyes and after that I noticed immediately my left eye had like a film over it, by that night the whole eye where should be white was red and my family said it looked like I had been out having a heaving drinking session ( but I dont drink !!! ) .
Also whilst away for 2 weeks had 4 cluster headaches so not sure what was with that. Luckily they were only mild and 2 my eyes were red and watery really bad for the next 24 hours and the other 2 I woke up in pain for appeox 2-3 hours and my eye was abit sore the next day but no blurred vision/wateryness.
So goes to show even with the same person the symptoms can vary slightly.
But 95% of the time I have terrible eyes that even friends/strangers can see the next day after I have had one just from looking at my left eye.
Hope you are all going well and not suffering terribly.
Patch
