Do woodpeckers get headaches?

As the title says, does the wood drilling have any health repercussions on a woodpecker? And also, is the skull built in such a way to prevent damages to the brain? 
Thanks!

No. They have multiple and very cool physical adaptations that absorb and distribute the impact.  The beak is very sharp and carves the wood more so than hitting it like a hammer.  They still hit hard (if you hit your head against a tree with just 1/10th of their force, it would likely kill you), but the beak’s cutting effect slows the forward motion as the beak enters the wood and lessens the blow as well as cartilage that softens/absorbs the impact.  The skull plates are not ossified together and slide along where they come together to absorb shock. The brain also differs from other birds - it is oriented to disperse the shock and more snugly secured within the skull, meaning there is less space around the brain so it sloshes less than ours.
