Overview
Headaches can cause a dull throbbing or an intense ache and pain in different areas, including the right side of your scalp, base of your skull, and your neck, teeth, or eyes.

While headaches can be uncomfortable, they’re unlikely to be “brain pain.” The brain and skull don’t have nerve endings, so they won’t cause pain directly. Instead, a wide range of factors can affect headaches, from lack of sleep to caffeine withdrawal.
