Hi. I’m a longtime lurker on the site but thought I would post as I have suffered with migraine aura for many years. I find that if, as soon as the sight distortions begin, I close my eyes and sit quietly for about twenty minutes, they go away and I don’t get the headache.
A few months ago I was in the middle of cooking dinner and ignored the zigzag lines etc, which I had three times in succession, and ended up with dreadful head pain and vomiting and was taken to A and E. I had a CT head which was normal, and they put it down to migraine. I had not had the headache for over 30 years. Now I am very careful to take my own advice and sit quietly! I hope this helps.
