The science of a headache.

When you get a headache, the pain isn't actually centered on the brain. It's all the muscles, nerves and blood vessels throughout your head and neck that take on the literal pain of a headache. Something triggers the brain to respond to the pain signals that produces two main chemicals that contribute to a headache. Norepinephrine and serotin causes the blood vessels around the brain to expand. From this pressure, comes pain. An ache in the head.

The throbbing feeling in your head that makes you think your brain is swelling is a faux impression that causes the feeling of pain, but the brain tissue doesn't feel pain like we do on our skin because it hasn't developed to know touch. This is how brain surgery is possible with a patient that is awake.

A migraine is a headache that comes and goes and has a throbbing pain that occurs in one spot in your head. A tension headache is more frequent and comes with pain feeling like pressure on the sides of your head. This type of headache can last several days.

I have had this headache.
For several days.

It's a pressure that hurts my head and my heart.
I do not merit this headache and I have inherited the heartache.

Life around me is so ugly, I wear my Introvert badge proudly.
