Hi, My Husband Had An AF Ablation 2 Days Ago.

Hi, my husband had an AF ablation 2 days ago. He is now suffering what appears to be a migraine with severe pain behind the eyes, he has never had migraines before this. There seem to be many people post-procedure with new onset of migraines, but no comments from doctors n this. How do we treat this? it is Sunday here, out GP is not available.
