Pain around the eye has dozens of possible causes, ranging from a simple stye to a sinus infection to rarer conditions like glaucoma. The location, type, and timing of your pain are the best clues to what’s going on. A dull ache that worsens when you bend forward points to your sinuses. A sharp, stabbing pain on one side that hits at the same time every day suggests a cluster headache. A tender red bump on your eyelid is likely a stye. Here’s a breakdown of the most common reasons and how to tell them apart.
Sinus Pressure and Infection
Your sinuses sit directly behind, below, and between your eyes. When they become inflamed or infected, the swelling presses against the thin bone of the eye socket. This creates a deep, aching pressure that feels like it’s coming from around or behind your eye rather than from your nose. The ethmoid sinuses, located between your eyes near the bridge of your nose, are especially common culprits because they’re so close to the orbit.
Sinus-related eye pain typically gets worse when you lean forward, bend down, or lie flat. You’ll usually notice other signs too: congestion, post-nasal drip, a reduced sense of smell, or thick nasal discharge. If the pain follows a cold that seemed to be improving and then got worse, a bacterial sinus infection is a strong possibility. Most cases clear up with decongestants, nasal saline rinses, and time, though a prolonged infection may need antibiotics.
Styes and Chalazia
A stye is a red, painful lump that forms at the base of an eyelash or just under the eyelid’s edge. It’s essentially a small infected oil gland, and it hurts right away. Your eyelid will feel tender to the touch, and the area may swell enough that the discomfort radiates to the surrounding skin. Styes are very common and usually resolve on their own within a week if you apply warm compresses several times a day.
A chalazion looks similar but behaves differently. It develops farther back on the eyelid, and at first you might not even notice it because there’s little or no pain. As it grows, the eyelid can become red and swollen, and you may feel a firm, round bump under the skin. Chalazia aren’t infections. They’re blocked oil glands that cause a slow buildup of fluid. They take longer to go away, sometimes weeks, but warm compresses help these too.
Cluster Headaches
Cluster headaches are one of the most intense pain conditions a person can experience, and they center squarely around one eye. The pain is burning, sharp, or stabbing, and it reaches full intensity within 5 to 10 minutes. Each attack lasts anywhere from 15 minutes to 3 hours. The strongest pain typically persists for 30 minutes to 2 hours.
What makes cluster headaches distinctive is their clockwork pattern. They tend to strike at the same time each day, often 2 to 3 hours after falling asleep, and repeat daily for weeks or months before disappearing for at least a month. On the same side as the pain, you may notice a watery or red eye, a droopy eyelid, a smaller pupil, a flushed face, or a stuffy or runny nostril. If this pattern sounds familiar, a doctor can diagnose it based on your symptoms and a physical exam alone, without imaging.
Migraines With Orbital Pain
Migraines frequently produce pain behind or around one eye, though the pain is usually throbbing rather than stabbing. A migraine attack can last 4 to 72 hours and often comes with sensitivity to light, nausea, or visual disturbances like zigzag lines or blind spots. Unlike cluster headaches, migraines tend to make you want to lie still in a dark room. Cluster headache sufferers often pace or rock because sitting still feels worse.
If your eye pain builds gradually, pulses with your heartbeat, and is accompanied by nausea or light sensitivity, migraine is a likely explanation.
Allergic Swelling
The tissue around your eyes is loose and thin, which makes it one of the first places to puff up during an allergic reaction. This type of swelling, called angioedema, affects deeper layers of skin and can appear within minutes. It causes mild pain and warmth in the area, along with noticeable swelling around the eyes, cheeks, or lips. You may also have hives elsewhere on your body.
Common triggers include insect bites, certain foods, medications, and environmental allergens. The key distinction from infection is that allergic swelling is usually symmetrical (both eyes), comes on fast, and isn’t accompanied by fever. It also tends to improve quickly with antihistamines.
Trigeminal Nerve Pain
The trigeminal nerve supplies sensation to your entire face through three branches. The upper branch covers your forehead and the area around your eye. When this nerve misfires, it can cause sudden, intense jolts of pain that feel like an electric shock. These episodes last only seconds to minutes but can repeat throughout the day.
What’s unusual about trigeminal neuralgia is that ordinary activities can set it off: touching your face, washing it, shaving, brushing your teeth, or even a light breeze. The forehead and eye area are affected less often than the cheek or jaw, but when they are, the pain can be startling in its intensity. This condition is more common in people over 50 and is treatable with medication.
Infections Around the Eye
Infections of the tissue surrounding the eye fall into two categories, and the difference between them matters. Preseptal cellulitis affects only the eyelid and skin in front of the eye. Your eyelid may be red, swollen, and warm, but your eye itself moves normally and your vision stays sharp. This type is more common in children and usually responds well to oral antibiotics.
Orbital cellulitis is more serious. It involves the tissue behind the eye, and the warning signs are clear: a protruding eye, pain when you try to move it, restricted eye movement, and in severe cases, reduced vision or changes in color perception. These symptoms suggest the infection is pressing on the optic nerve. Orbital cellulitis needs urgent treatment, typically in a hospital with intravenous antibiotics.
Acute Glaucoma
Acute angle-closure glaucoma happens when fluid pressure inside the eye spikes suddenly, sometimes reaching three to four times normal levels. It causes severe pain in and around one eye, blurred vision, rainbow-colored halos around lights, nausea, and vomiting. The eye is usually red, and the pain comes on rapidly.
This is an emergency. Without treatment within hours, the high pressure can permanently damage the optic nerve and cause irreversible vision loss. If you’re experiencing intense eye pain with blurred vision and halos, especially if it came on suddenly, get to an emergency room.
Dental and Jaw Problems
Pain around your eye can originate from your teeth or jaw. The roots of your upper molars sit very close to the floor of your maxillary sinus, which borders the bottom of your eye socket. An infected upper molar can spread inflammation upward through the sinus and into the orbital area. TMJ dysfunction, where the jaw joint is inflamed or misaligned, can also refer pain upward into the temple and around the eye.
If your eye pain coincides with a toothache, recent dental work, or jaw clicking and soreness, the source may be lower on your face than you think. Treating the dental issue typically resolves the referred pain.
Eyestrain
For many people searching this question, the answer is simpler than any of the above. Digital eyestrain from prolonged screen use causes a tired, aching sensation around both eyes, along with headache, dry eyes, and blurred vision at the end of the day. It’s not dangerous, but it’s uncomfortable. Following the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) and adjusting your screen brightness can make a meaningful difference.
Signs That Need Immediate Attention
Most causes of pain around the eye are manageable and not emergencies. But certain combinations of symptoms signal something that needs same-day or emergency evaluation:
- Sudden vision loss or blurring in one eye, with or without pain
- A bulging or protruding eye with pain when moving it
- Severe eye pain with halos around lights, nausea, or vomiting
- New flashing lights or a shower of floaters in one eye
- Eye pain after a chemical splash or injury to the eye
- High fever with eyelid swelling that’s getting worse, not better
Any of these patterns can indicate conditions where hours matter for preserving your vision.
