Sinusitis affecting one sinus
Inflammation and swelling in one sinus cavity build pressure. This pressure could radiate pain to one side of your face or forehead.
Dental issues
Problems like tooth decay or jaw joint dysfunction could refer pain to one side of the head. This is often felt as a dull ache or sharp pain.

Inflammation of arteries, usually in the temples, causes swelling and pain. This could lead to throbbing headaches localized to one side and scalp tenderness.
