Brief Answer:
Get examined by a neurologist

Detailed Answer:
Hello,
I have gone through your question and understand your concern.
It is not possible to rule out brain lesion clinically.
Any history of severe recurrent vomiting, persistent visual abnormalities, speech difficulties, weakness can be an indicator of brain lesion.
Other possibility can be migraine headache if previous history of such headache exists.
Migraine headache is throbbing, unilateral, associated with nausea, vomiting, sensitivity to light or sound.
Pain killers like aceclofenac or diclofenac or naproxen can be taken for acute attack.
Recurrent episodes needs to be managed by prophylaxis medications like amitriptyline or flunarizine or divalproate or topiramate.
Hope you found the answer helpful.
