Neck pain plus headache is usually one problem - the neck referring pain into the head from posture, tension, or stiff upper joints. Headache with fever and a stiff neck that will not bend is an emergency.

Common questions
Why do I get neck pain and headaches together?
Neck pain and headache together are usually one problem, not two: the neck's upper joints, muscles, and nerves refer pain straight into the head - doctors call it cervicogenic headache. The classic pattern: pain starting at the base of the skull, one-sided more often, spreading to the temple or behind the eye, with a stiff, sore neck and tenderness where neck meets skull. The drivers are everyday: hunched screen posture - the forward-head position loads the upper neck joints for hours - stress clenching, a bad pillow, and old whiplash injuries. MedlinePlus notes most neck pain is muscular and postural and improves with self-care. The self-care that works: fix the workstation - screen at eye level, shoulders back; move every 30 to 60 minutes; heat on the neck muscles; gentle range-of-motion stretches; and a pillow that keeps the neck neutral. Physical therapy is the proven next step for persistent cases. The red flags that change everything: headache with fever and a stiff neck you cannot bend to your chest - meningitis pattern, emergency; neck pain and headache after an injury; pain with arm numbness, weakness, or shooting pain down the arm; and headache that is the worst of your life.
