Hi. We can certainly continue after this if you'd like;
This could be a migraine but usually there are other symptoms like blurring vision, nausea, sensitivity to light, etc.
That said, the distribution of the pain is also consistent with trigeminal neuralgia--inflammation of the cranial nerve that courses along that same path.
However any significant headache like this one that is new and out of the blue needs immediate medical evaluation since it could also be a leaking intracranial aneurysm, so I strongly suggest you see a doctor right away for an exam
