is there a beneficial or evolutionary advantage to headaches/migraines or are they just an annoying by product of evolution and being human?

Question

my head hurts and I just got curious about this.

In: Biology

Answer 1

All pain points towards something being wrong which needs fixing.

A lot of headaches are a result of blood pressure imbalance. In the absence of such (annoying) ‘notifications’, we run the risk of rupturing blood vessels or falling short of oxygen in the brain.
