Headache Behind the Eyes: 7 Causes and When to See a Doctor

Pain felt behind or around the eyes is one of the most frequently reported headache symptoms — yet most patients assume it is an eye problem. In the vast majority of cases, the eyes themselves are normal. The pain is coming from the brain's pain pathways, not the eye.

7 Most Common Causes

1. Migraine

Migraine commonly causes pain behind one eye, often with throbbing, nausea, and sensitivity to light. The trigeminal nerve (which supplies the eye and forehead) is central to migraine pain generation. If your eye headache is associated with nausea, light/sound sensitivity, or lasts 4–72 hours — migraine is the most likely diagnosis.

2. Tension-Type Headache

A tight, pressing headache felt across the forehead, temples, and behind both eyes. Often worse by late afternoon, worsened by prolonged screen use, and related to posture and stress. Usually responds to paracetamol and rest, but daily tension headache requires preventive treatment.

3. Cluster Headache

Cluster headache is rare but distinctive — an extremely severe, one-sided pain centred behind one eye, typically lasting 15–180 minutes, occurring multiple times daily in "clusters" of weeks or months. Often associated with a watering eye and blocked nose on the same side. This is the most severe primary headache known — called "suicide headache" in older literature. It requires specialist neurologist treatment.

4. Sinusitis

Inflammation of the sinuses (especially the frontal and ethmoid sinuses, which lie close to the eyes) causes facial pressure and pain that radiates behind the eyes. True sinus headache is accompanied by nasal congestion, thick discharge, and tenderness over the cheeks or forehead. Pure sinus headache without nasal symptoms is actually often migraine misdiagnosed.

5. Digital Eye Strain (Asthenopia)

Extended screen use causes the eye muscles to fatigue, producing aching pain around and behind the eyes, often with blurring and difficulty focusing. This is not a neurological problem but a muscular one — it resolves with rest and screen breaks (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds).

6. Uncorrected Refractive Error

People who need glasses (or whose prescription has changed) often strain their eyes to focus, producing headache behind the eyes, particularly during reading or screen use. An ophthalmologist check and updated glasses prescription often resolves this completely.

7. Raised Intracranial Pressure

Conditions that raise pressure inside the skull (certain medications, idiopathic intracranial hypertension, very rarely a tumour) can cause headache that is worse in the morning, worsens when lying down, and may be associated with visual changes or pulsatile tinnitus (a whooshing sound in the ears). This requires urgent investigation.

When to See a Neurologist Urgently

• Sudden, severe headache behind the eye — "worst headache of my life" (thunderclap headache)
• Headache with vision changes, double vision, or eye movement problems
• Headache worse when lying down or on waking
• Headache with a painful, red eye (could be acute angle-closure glaucoma — ophthalmological emergency)
• Any new, severe, or rapidly worsening headache

For recurring headache behind the eyes, an appointment with a neurologist provides an accurate diagnosis and a targeted treatment plan. Call Sri Anand CNC on +91 90633 66983.
