Hi I had gone through your query. If headache is persist after taking medicines then require investigations. 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. But go for reports 1st then consult neurologist if require. I hope i have answered your query. Thank you. Get well soon.
