Thanks for writing in.
I am a cardiologist and I read your question with diligence.
Closure of atrial septal defects by Amplantzer device(s) has no way related to the onset of Migraine. Absolutely, no relation whatsoever. It is mere coincidence that Migraine Headache
started in your son in the same month he had undegone a procedure for heart under local anesthesia
Therefore, I will urge you to displel this notion. Write full details a) what precipitate the headache b) is there any aura or perception that headache is going to come c) what exactly accompanies the headache or shortly thereafter d) what relieves it and if untreated how long it lasts. Meanwhile, get an appointment from your doctor, who may start treatment or refer you to a neurologist
. That is the best course of action.
With Best Wishes
