Thanks for posting this question in HCM
Let me explain you that a given medical symptom is due mainly to various causes and the aim of the physician is to find out the exact cause and deal accordingly rather than simple assumption.
Back to your questions i understand that you have headache and photosensitivity
which i think could be migraine. Let me deal your problem as follows
1. Let me tell you that headache can be due to various reasons like migraine, brain tumor
, brain infections, problems in the blood vessel of the brain etc. One strong possibility is that the constellation of symptoms that you have described could be due to migraine. However, one has to understand that migraine is a diagnosis of exclusion that means other treatable conditions that result in headache which i have listed above need exclusion before the diagnosis of migraine is made. You will benefit from the following approach
1. During acute attack: this will improve with analgesics, sumatriptan nasal spray
and relaxation, to avoid the precipitating factor like stress, coffee, perfumes which you have to find out. Avoid continuous use of laptop and take pause in between. Some people with migraine have visual sensitivity and this can trigger an attack. Better to avoid these glares and yoy can use dark glasses too.
2. Medicines that can modify the course of migraine will be helpful like valproate (not good in females), topiramate
You can meet a local neurologist
who will evaluate you by clinical examinations and will determine if you need a scan or not. If both these are normal, you will certainly benefit with the above approach
Get well soon
