ELI5: Why do people with severe Migraines or Cluster headaches feel like drilling their head is a perfectly sane idea at the moment?

My SO has been getting really bad headaches(Luckily not migraines/cluster) but looking in the internet about them, and from what she told me,  people experiencing them seem to consider hurting their head in some way a very sane and logical solution. But, why?

I get migraines and cluster headaches. First off there are different types and different causes. The type that makes you want to drill into your head is usually due to sinus pressure. it feels like something is pushing against your skull and opening a hole will release the pressure. Now, noone really wants to drill into their head literally they just want the pain to stop. Generally putting counter pressure on the sinus will numb the pain.

Also interesting fact. there are migraines that don't involve any pain. Extremely photosensitive people in certain light can't focus their eyes, may loose balance, or get nauseous. All of this and no headache.

Other causes include constricted veins. High blood pressure. Injury or tightness in the upper neck muscles. And concussion history.

If you never had a history of migraine and suddenly get them get in touch with your doctor asap. They could be the sign of something more serious.
