A swollen bridge of the nose usually points to one of a handful of causes: a bump or injury, a sinus infection, a skin infection, or less commonly, an allergic reaction or autoimmune condition. The bridge sits over thin nasal bones and, just in front of them, cartilage. Because there’s very little padding between the skin and these structures, even mild inflammation in the area becomes visible quickly.
Figuring out the cause comes down to a few key details: whether you had any recent trauma, how fast the swelling appeared, whether it’s painful or warm to the touch, and whether you have other symptoms like congestion, fever, or vision changes.
Injury to the Nose
This is the most straightforward explanation. A knock to the face from a ball, a fall, a door, or even rough play with a child can cause soft tissue swelling over the bridge within minutes. Signs of a broken nose include swelling in and around the nose, bruising around the nose or eyes, and a crooked or misshapen appearance. You don’t always hear or feel a crack. Sometimes a fracture only reveals itself once the swelling goes down a few days later and the bridge looks slightly off-center.
If you’ve had a hit to the nose and notice that one or both sides of the inside feel boggy, soft, and completely blocked, that could be a septal hematoma, which is a pocket of blood collecting inside the nasal septum. The area will feel soft when you press on it gently, and you’ll have significant congestion along with painful swelling. A septal hematoma needs medical attention quickly because untreated, the trapped blood can damage the cartilage and permanently change the shape of your nose. Any nasal injury that results in persistent congestion and pain warrants a visit to your provider.
For a straightforward bump without signs of fracture or hematoma, the swelling typically goes down within a few days. Ice the area for 20 minutes at a time, every one to two hours while you’re awake, with a cloth between the ice and your skin.
Ethmoid Sinus Inflammation
Your ethmoid sinuses sit just behind the bridge of the nose, between your eyes. When they become inflamed from a cold, allergies, or a bacterial infection, the pressure and swelling can radiate outward and make the bridge itself feel puffy, tender, or tight. The hallmark symptom is pain or pressure right at the bridge of the nose, often alongside nasal congestion, postnasal drip, and sometimes a low-grade fever.
This type of swelling tends to build gradually over a day or two rather than appearing suddenly. It often gets worse when you lean forward. If you’ve had a cold for more than 10 days and the bridge of your nose is swollen and sore, the infection may have settled into the ethmoid sinuses. Most sinus infections resolve on their own, but bacterial cases that drag on or worsen after initial improvement sometimes need antibiotics.
Skin Infections
Infections that start inside the nostrils can spread upward and outward toward the bridge. Nasal vestibulitis is an infection of the hair follicles just inside the nostril opening. It often shows up as pimples or sores inside the nostrils, along with pain, swelling, discoloration, itching, and sometimes yellow crusting around the septum. Picking at the nose, plucking nose hairs, or frequent nose blowing can set it off.
In more severe cases, the infection can progress to a boil inside the nostril and then to cellulitis, a deeper bacterial skin infection that spreads into surrounding tissue. Cellulitis at the tip or bridge of the nose causes redness and warmth that expands outward, and it can eventually reach the cheeks, other areas of the face, or in rare cases the bloodstream. If the skin over your bridge is red, warm, increasingly painful, and the redness is spreading, that’s a sign the infection is moving beyond its starting point and needs prompt treatment.
Allergic Swelling
Angioedema is swelling in the tissue just beneath the skin, caused by fluid leaking from small blood vessels. It most commonly affects the lips, eyelids, tongue, hands, and feet, but it can show up anywhere on the face, including the bridge of the nose. The swelling is typically soft, not red, and not particularly painful, which distinguishes it from an infection.
Triggers include food allergies, drug reactions, insect stings, and latex exposure. Allergic angioedema usually appears within minutes to a couple of hours after contact with the trigger. If the swelling is isolated to the bridge and appeared after you started a new medication, ate an unfamiliar food, or were stung by an insect, an allergic reaction is a likely explanation. Swelling that also involves your throat, tongue, or makes it hard to breathe is an emergency.
Cysts and Bumps on the Skin
A localized, dome-shaped bump on the bridge that you can move slightly under the skin may be a sebaceous cyst. These are smooth, round masses that range from a few millimeters to several centimeters. They appear commonly on the face and are usually painless unless they become infected, at which point they turn red, tender, and warm. A new skin swelling that persists for more than two weeks is worth having a provider look at, especially if it’s painful.
Acne cysts or boils can also develop on the bridge of the nose, particularly if you wear glasses. Pressure and friction from frames create a warm, occluded environment where bacteria thrive. These tend to be red, tender, and clearly centered around a single point rather than spread across the entire bridge.
Rare Autoimmune Causes
If swelling at the bridge keeps coming back or is accompanied by pain in your ears, joints, or windpipe, a rare condition called relapsing polychondritis could be involved. This autoimmune disorder causes the immune system to attack cartilage throughout the body. Over time, repeated episodes of inflammation can cause the cartilage at the bridge of the nose to collapse, creating a characteristic “saddle nose” deformity where the bridge dips inward. It also commonly causes red, swollen, painful ears (sparing the earlobes, which have no cartilage). This condition is uncommon, but the pattern of cartilage inflammation at multiple sites is distinctive.
How to Tell What’s Causing Yours
A few patterns help narrow it down:
- Sudden onset after impact: Trauma. Look for bruising, asymmetry, and difficulty breathing through one side.
- Gradual onset with congestion and facial pressure: Likely ethmoid sinusitis, especially during or after a cold.
- Red, warm, spreading skin changes: Infection, possibly cellulitis. More urgent if you also have fever.
- Soft, painless puffiness that appeared within hours: Allergic angioedema. Think about new exposures.
- A single movable bump: Cyst or localized skin lesion.
- Recurring episodes with ear or joint pain: Possible autoimmune cartilage condition.
Most cases of nasal bridge swelling are either minor injuries or sinus-related and resolve within days. Swelling that’s rapidly spreading, accompanied by fever, involves the eyes or vision, or follows significant facial trauma deserves same-day medical evaluation.
