Thanks for your query. Photophobia
, headache are usually seen with migraine
. Don't think about brain tumor
unless as you don't have vomiting
. But if your still worried about that, then you can go for CT brain. As per my knowledge you might be suffering from migraine, i suggest you to consult ENT and ophthalmologist to rule out other causes of headache. If they suggest CT brain they you can go ahead.
