Hi I understand your concern. You need to investigate yourself. 1st thing is require is fundas examination. It will shows any papillodeama that suggest raise in interracial tension. MRI brain will helpful to rule out any pressure producing lesion or space occupying lesions. If all report come normal then we have to think about migraine associated with tension type headache dor which tab amitryptiline 25 mg is very beneficial. Take simple analgesic as and when require if pain is very severe. But go for reports 1st then consult neurologist if require. I hope i have addressed your query. Still if you have query then feel free to ask. Thank you
