Headaches and migraines can be caused by many conditions, such as arthritis, inflamed joints in the neck, muscle tightness/strain, pinched nerves in the cervical spine, disc injury or degeneration or physical trauma that affects the brain.
Tension Headaches —
This happens when muscles constrict due to tension, causing pressure pain typically felt in the forehead and/or back of the head.
Migraine Headaches —
More intense than regular headaches, migraines tend to cause throbbing pain in the forehead or one or both temples. They may result in nausea, vomiting, light sensitivity and blurred vision.
