hi
welcome to our site
read your query
that is a very significant question
and i appreciate your problem
i will try my best to answer your query
i would have suggested you tell me exactly what the symptom is
and not what you feel the diagnosis is
tell me the character of pain
not tension type headache
and what trauma have you had
to think of traumatic encephalopathy
a long standing headache could simple be a migraine
in fact
photophobia you described is a feature of migraine
and quickly rising and settling pain
could be both cluster
headaches and migraines
i also think one should rule out space occupying lesions
and therefore i suggest an
mri of brain
with contrast if needed
i hope this helps you
inform the reports mentioned above (if any)
so i can be of help further
best of luck
(please do understand that some problem remains as
online texting cuts down history and examination
thereby reducing the effect and efficiency
and increases reliance on tests)
(If the answer has helped you, please indicate this)
