It's rather inconclusive whether PFO is the cause of any headache problems, though PFO closure has been shown to sometimes improve HA symptoms. Because of the uncertain association between PFO and headache the only way to know if you have PFO is to be tested. If you neurologist feels that PFO closure might be a good treatment option for you then you should consider getting checked. The test is an outpatient procedure but you still have a tube stuck down your throat.
But anyway, as with most things you best option is to discuss this with your doctor. Particularly since there's no other way to tell than to be tested.
