> Pain is strictly a physical sensation.

Hard to tell that to those with lost limbs who suffer from ghost pain.

Do not be fooled by the term "ghost". The pain is still real, and experts now agree it is coming from both the brain and spinal cord [1]. Just like optical illusions, the mind can play many tricks on us. Just because the pain feels like it is coming from a non-existent limb does not mean that that is where it is actually coming from.

So uhh, what exactly is pain? Is it the feeling? Is it the physical damage? Is it a warning about damage? Is it the fear of damage (as in broken hearts etc.)?

I'm not a biologist or anything, but I'd define it simply as a signal from your nervous system to your brain.

So.. a thought? An emotion? Or a sensation?
