As a child, I had quite debilitating migraines on a regular basis. Perhaps monthly in adolescence, settling down to twice a year in early adulthood and then rarely after my twenties. There was always a visual aura followed by a headache. In later life, I found that if I took a paracetamol as soon as the aura appeared and also ate something to increase my blood sugar (?), I could avoid the headache, but would feel drained for the rest of the day.
I can’t remember my last migraine before the AF diagnosis, but it was many years ago. A few hours after my ablation in 2017, I had a migraine aura, but it was not accompanied by any feelings of illness. It was also a different shape to my usual aura; this was a grey cross in the centre of my vision with two stripes across the bottom and right side of my peripheral vision. This is quite normal post-ablation.
This year, I have had four migraine auras: one in July, two in August and one yesterday. These are a little different from my original auras. Originally, they were quite compressed into a small area just off the centre of my vision, but these new ones are wider and further out. I only managed to take a tablet for the first one of these recent migraines, but none resulted in a headache.
This is a little puzzling; has AF or the ablation changed my
migraine susceptibility or how I experience them? Is it possible that these are a normal change
