Chronic daily headaches. mri came back normal. taking nortriptyline 10mg for the pain but not working. pain killers don't help. what is this headache?

Treatment options: Chronic headaches could be from vascular causes most of the time. MRI may not show any abnormality If nortryptiline does not work in your situation, there are multiple other regimen of treatments available. You might want to consult a neurologist

Chronic daily HA: This is a real diagnosis. It is hard at sometimes to treat and very frustrating. It may be some type of migraine or a combination of stress tension headache with migraine components. Have you seen a neurologist? This is important to do and also important of how often you actually have the headache. The nortriptyline is a basic start and this is at a low dose. Neg MRI means no tumor. Best wishes.
