A headache refers to pain or discomfort experienced in the head or upper neck area. It can have various causes, including tension, stress, dehydration, lack of sleep, sinus infections, or underlying health conditions like migraines. Interestingly, different areas of head pain can signify different things. For instance, pain concentrated in the temples might indicate tension headaches, while throbbing pain on one side of the head could signal a migraine. Additionally, pain focused behind the eyes might suggest a sinus headache. Treatment often involves rest, hydration, over-the-counter pain relievers, and addressing any underlying issues contributing to the headache.
