Headache Behind the Eyes: Sinus, Migraine, or Something Else

Pressure or pain behind the eyes gets labelled a sinus headache more often than any other type. Studies of people who self-diagnose sinus headache find that the majority actually have migraine. The distinction matters, because the treatments are completely different.

The four main causes

Migraine

The most common cause of pain behind the eyes in adults. Migraine does not always mean a one-sided throbbing headache with visual aura. It frequently causes facial pressure, nasal congestion, and watery eyes — which is exactly why it gets mistaken for sinus trouble.

Clues: sensitivity to light or sound, nausea, worsened by movement, comes in episodes lasting 4 to 72 hours, and a personal or family history of headaches.

Eye strain

Extended screen work, an outdated glasses prescription, or uncorrected astigmatism causes a dull ache behind the eyes that builds through the day.

Clues: worse in the afternoon and evening, better on weekends or after a break, comes with dry or tired eyes and blurry vision at distance after close work.

Tension headache

A band-like pressure that can extend behind the eyes, driven by neck and scalp muscle tension.

Clues: both sides, steady pressure rather than throbbing, tight neck and shoulders, no nausea, not made worse by movement.

Sinus infection

Real sinus headache exists but is less common than assumed and rarely occurs without other clear sinus symptoms.

Clues: thick discolored nasal discharge, reduced sense of smell, pain worse when bending forward, tenderness when tapping over the cheeks or forehead, and a recent cold that never fully cleared. Our article on sinus infection versus cold covers the crossover point.

Quick comparison

Less common causes worth knowing

• Cluster headache. Severe pain behind one eye, with a red watery eye and blocked nostril on the same side. Attacks last 15 minutes to 3 hours and often strike at the same time each day. This is intensely painful and needs specialist treatment.
• Glaucoma (acute). Sudden severe eye pain, blurred vision, halos around lights, a red eye, and nausea. This is an emergency — permanent vision loss can occur within hours.
• Giant cell arteritis. In adults over 50, new headache with scalp tenderness, jaw pain when chewing, and vision changes. Needs same-day assessment.

What helps, by cause

Migraine: a dark quiet room, an anti-inflammatory taken early, hydration, and consistent sleep. If you get more than four a month, prescription prevention is worth discussing.

Eye strain: the 20-20-20 rule — every 20 minutes, look at something 20 feet away for 20 seconds. Get your prescription checked. Reduce screen brightness to match the room.

Tension: neck stretches, heat on the shoulders, addressing desk posture.

Sinus: saline rinse, steam, and time. Most sinus infections are viral and clear on their own — see how long a sinus infection lasts without antibiotics.

For pain relief in any of these, see our guide to acetaminophen versus ibuprofen.

Go to the emergency room for

A sudden severe headache that peaks within seconds, headache with vision loss, headache with a stiff neck and fever, headache after a head injury, headache with confusion or weakness on one side, or a red painful eye with halos around lights.
