Chronic illness: migraine

The causes of headaches are really diverse, aren't they?

Just by searching, a lot of results come up.

But I have had migraines since I was young.

They say they don't get sick every day, but they go about their daily life.

Whenever I get sick, I have migraines that last for several days.

It keeps hurting even after I wake up, so it's subtly annoying.

There is no problem when a brain CT scan is taken.

Have you found the cause after suffering from a headache and then feeling better?

Please share it with me. I want to try everything.
