Scalp tenderness is linked with many forms of headaches. In particular, scalp tenderness is linked with headaches involving the nerves that run from the back of the neck to the forehead.
Conditions that cause these nerves to swell or restrict can result in pain that moves throughout the head, neck, and scalp. According to Johns Hopkins University, this pain can appear as hot, intense, electric-like shocks.
The scalp becomes so sensitive for some people that even a light touch can be painful. In others, the scalp goes numb. This form of nerve pain is rare and usually caused by injury or a spontaneously pinched nerve. Headaches involving these nerves are far more common, however.
