Hello,
I have studied your case.
As per your history there is possibility of headache due to
migraine.
Migraine usually involves half part of your head.
Pain is severe and aggravated by triggering factors like fast, irritant smell, travelling.
If you were my patient, I would clinically confirm diagnosis.
After clinical examination, medications for migraine like sumatriptans can be started consulting your doctor.
Another possibility of headache due to
hypertension, but it is not unilateral.
You can check your blood pressure consulting your doctor.
Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
Wishing you good health.
Take care
