I have noted with interest occurrences of migraine aura amongst our group immediately following radiofrequency ablation. I had 5 episodes of a transient nature the next day, a couple more the first week then at intervals every couple of weeks, and finally a break of 2 months. Its now nearly 6 months since the ablation. I believe there is a theory it's a result of the transseptal puncture during the ablation procedure. However I thought the latter should be healed by now, so was dismayed at its return recently. Did anyone else experience the same time pattern and will it disappear eventually? I must add that i rarely have an accompanying headache, but have occasional headache without aura. Look forward to hearing from members. I understand the condition is also known as scintillating scotoma with zig zag flashing shapes which prevent you from pursuing any activity such as reading, driving etc. I just sit still and wait for it to pass and it generally does within 30 minutes.
