Expert Answer: Are my migraines related to my patent foramen ovale (PFO)? Will treating or closing the PFO help my migraines?
There seems to be a relationship of PFOs and migraine, particularly if there is aura. However the trials so far have been disappointing in that it is very unclear that the risks involved in the treatment justify the benefit. So very few headache experts at this point are recommending evaluation and therefore treatment for this problem.
Can you tell when a migraine attack is coming?
