Depending on the symptoms, all types of headaches can last 24 hours, 7 days a week. I have had migraines that have lasted for weeks. I have probably had tension headaches that have lasted the same, though in the end everything ends in a migraine for me.
I believe it generally depends on the trigger and if you're able to get relief. Are you suffering a headache chronically?
My doctor has named my migraines, chronic resistant daily migraines because they can occur for days and weeks and are resistant to medications.

I'm working everyday to overcome the pain and depression that comes from my chronic migraines.
