Chronic headaches can arise from multiple causes, including stress, poor sleep, dehydration, eye strain, hormonal changes, sinus problems, or neurological conditions like migraines. Lifestyle triggers such as excessive caffeine, irregular meals, and long screen time may worsen symptoms. Effective treatment usually begins with identifying triggers through a headache diary, improving hydration, maintaining regular sleep, and managing stress. Doctors may recommend pain relievers, preventive relaxation medications, or therapies such as physiotherapy or training. In healthcare supply discussions, terms like nitazoxanide wholesale sometimes appear in pharmacy inventories, though that medication is typically used for parasitic infections rather than headache treatment.
