It seems from the history that you are having headaches
and diagnosed by your doctor as tension headache
The pain because of aneurysm
will be very acute and associated with nausea, vomiting
and other signs or raised intracranial tension.
Since you are not having any of these symptoms this is unlikely to be pain associated with aneurysm.
Since you have mentioned that headache typically worsens with physical activity this looks like tension headache only.
