Hi I understand your concern. You need to investigate yourself. Do you have vision difficulty? Do you have problem in walking? If yes then 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 for which tab amitryptiline 25 mg is very beneficial. But go for reports 1st then consult neurologist if require. Thank you.
