Tension headaches are the most common type of headache.
These headaches can actually come from different places in your head that have pain structures and are very sensitive. Some of these structures are located in the back portion of your head, called the dura mater. There are branches from nerves and large blood vessels located here that can be associated with tension headaches. The headaches you experience are caused by compression, displacement, or swelling of these structures. Sometimes the pain can come from different structures located on or around your brain as well, such as your scalp, neck, or muscles around your eyes.
