Headache and sensitivity to light

Light sensitivity, also called photophobia, may accompany a throbbing or pressure-like headache. Migraine can bring nausea, visual changes, or a need to rest in a dark, quiet room. A viral illness, sinus symptoms, heat exposure, or not drinking enough can also make head pain and light discomfort occur together. Eye strain from prolonged screen use may add aching around the eyes. The symptom pattern, onset, triggers, and other features matter more than the light sensitivity alone.

Move to a calm room with gentle lighting, pause screen use, drink fluids if you can, and rest. Avoid driving while vision is uncomfortable or the headache affects concentration. Note when the pain began, whether it is one-sided, and any nausea, fever, rash, eye pain, weakness, or visual loss. A clinician can use this history to decide whether examination, eye assessment, or other care is appropriate.

Get emergency help for a sudden severe headache, new weakness or numbness, confusion, fainting, trouble speaking, a seizure, a stiff neck with fever, or repeated vomiting. Seek prompt medical care for a new headache after a head injury, severe eye pain, or ongoing visual loss. Arrange a medical review when episodes recur, steadily worsen, or interfere with normal activities.

Could this pattern fit migraine or another cause? Do my medicines, vision, sleep, hydration, or screen habits contribute? What warning signs should change my plan?
