One-sided nose swelling symptoms

Swelling is often a normal reaction your body has in response to an injury. It appears as an abnormal enlargement of a body part, and it can either be localized to a small area or more general. Swelling can be due to a variety of causes but typically occurs when fluid (including blood) collects in a particular area. However, swelling can also be due to abnormal cell growth.

In small body parts, like your nose, swelling can be hard to ignore. One-sided nose swelling can occur on the inside or outside of your nose,and while the symptoms of each kind of swelling overlap, there are some differences you might notice depending on the kind of swelling you have.

Inside the nose

Symptoms associated with one-sided swelling inside your nose may include:

Outside the nose

Symptoms associated with one-sided swelling outside your nose may include:

  • Pain or tenderness around the swelling
  • Distorted or misshapen nose
  • Bleeding

Either cause of one-sided nose swelling may also be associated with fever, redness and/or warmth of the affected area.

Duration

The duration of your swelling episode may be short- or long-term.

  • Depending on the cause, one-sided nose swelling may last only a few days before resolving on its own or you may notice it persist for a week or more.
  • If your nose swelling is persistent, it may also shrink or grow over time.

Is one-sided nose swelling serious?

The severity of the swelling may vary, judging by the following details.

  • If it is self-resolving: A small nose swelling that resolves on its own is typically not serious.
  • If you also have a fever: A large nose swelling that is associated with redness, pain, and warmth that does not seem to be resolving should be seen by a medical professional, especially if you also have a fever.
  • If it is growing or fixed: A nose swelling that grows over time and does not shrink or resolve on its own should be evaluated by a medical provider.



One-sided nose swelling causes

The good news about one-sided nose swelling is that the potential causes for it are limited and fall into a few categories:

Infections

Possible causes of nose swelling related to infections may include:

  • Skin infection: A bacterial or fungal infection of the skin of your nose either on the outside or inside of your nostril can cause swelling. Skin infections usually occur when a small cut or injury to the skin is exposed to bacteria.When this infection reaches deeper layers of the skin it is called cellulitis. Cellulitis can appear as a red, swollen area that feels warm and tender. Sometimes a collection of pus forms as your body tries to fight the infection and this is called an abscess.
  • Upper respiratory infections: An upper respiratory infection is more commonly referred to as a cold and is caused by viruses. Sometimes, an upper respiratory infection can cause internal swelling of the nose as your body tries to mount a response to the virus. This can lead to feelings of congestion and tenderness in and around the area of your nose, plus all the other symptoms that come with colds like a runny nose, sneezing, difficulty breathing, and reduced sense of smell.

Trauma

Anything that causes injury to the nose such as a direct hit to the face, surgery, car accident, or a nose piercing can lead to swelling of the outside of the nose. This swelling occurs as blood or fluid collects under the thin skin of your nose and can also be associated with deformity of the nose, especially in cases in which the trauma also leads to a broken nose.

Systemic disease

Nose swelling may also be caused by disease, such as:

  • Autoimmune disease: An autoimmune disease occurs when the immune system which usually works to protect you against diseases and infections instead starts to attack the healthy cells that make up your body. Some autoimmune diseases attack the cells that make up your nose and can cause internal swelling along with other symptoms like bleeding, deformity, pain or tenderness, reduced sense of smell and difficulty breathing through the affected side.
  • Allergic disease: People with allergies can also have generalized internal swelling of the nose leading to congestion and difficulty breathing through the affected side, and other symptoms like clear runny discharge from the nose, itchy/watery eyes, and sneezing.

Abnormal cell growth

Sometimes one-sided nose swelling can be caused by the abnormal growth of cells in your nose. Sometimes these growths are non-cancerous, soft, painless swellings called nasal polyps. Other times the cells that grow out of control might form a tumor; several types of tumors can grow in the nose, although nasal tumors are very rare. Polyps and tumors can both lead to nasal blockage and the associated symptoms that occur like congestion and difficulty breathing. Some tumors of the nose can also be associated with bleeding, a decreased ability to smell and sinus infections.

Relapsing polychondritis

Relapsing polychondritis is an episodic, inflammatory and destructive disorder involving primarily cartilage of the ear and nose. It can also potentially affect the eyes, tracheobronchial tree, heart valves, kidneys, joints, skin, and blood vessels.

You should visit your primary care physician for mild severity of relapsing polychondritis. Medications such as NSAIDs and steroids are generally prescribed.

Nose or sinus tumor

A tumor in the nose or one of the sinuses occurs due to abnormal growth of the cells lining the inside of the nose and sinuses. These tumors are rare and can cause symptoms like congestion or blockage, nose bleeds and sometimes facial pain or swelling.

You should visit your primary care physician to discuss your symptoms and to get further tests done. Referral to an ENT surgeon is likely needed.

Rarity: Ultra rare

Top Symptoms: new headache, congestion, vision changes, ear fullness/pressure, ear pain

Symptoms that never occur with nose or sinus tumor: improving congestion

Urgency: Primary care doctor

Iatrogenic nose condition

Surgery of the nose or nose piercing can result in side effects ranging from infection, pain and swelling to numbness and decreased sense of smell.

You should contact a healthcare provider to decide whether your symptoms need further examination and treatment. If you have signs of an infection, it is likely a course of antibiotics will be prescribed.

Common cold

The common cold is a contagious viral infection that can cause cough, congestion, runny nose, and sore throat. Most adults catch two to three colds per year, and kids can get more than eight colds each year.

Rest and drink plenty of fluids. Colds are contagious and can easily spread to other people, so if possible, avoid close contact with others, such as hugging, kissing, or shaking hands. Colds typically resolve within 7 to 10 days.

Cellulitis

Crohn's disease is an inflammation of the bowel. It is caused by a faulty immune system response which makes the body attack the lining of the intestines.

The disease usually appears before age thirty and can affect anyone. Those with a family history may be most susceptible. Smoking is a known risk factor.

Aggravating factors include stress, poor diet, and nonsteroidal anti-inflammatory drugs such as ibuprofen and aspirin.

Early symptoms usually develop gradually, but can appear suddenly. These include fatigue, loss of appetite, fever, mouth sores, diarrhea, abdominal pain, and blood in stool.

Untreated Crohn's disease can cause ulcers throughout the digestive tract as well as bowel obstruction, malnutrition, and deteriorating general health.

Diagnosis is made through blood test and stool sample test. Colonoscopy, CT scan, MRI, endoscopy, and/or enteroscopy may also be used.

Crohn's disease cannot be cured, but can be managed through reducing the inflammation. Antibiotics, corticosteroids, and immune system suppressors may be tried. Excellent nutrition, vitamin supplements, smoking cessation, and reduction in stress can be helpful.

Rarity: Uncommon

Top Symptoms: fever, chills, facial redness, swollen face, face pain

Symptoms that always occur with cellulitis: facial redness, area of skin redness

Urgency: Primary care doctor

Bacterial sinus infection (sinusitis)

Acute bacterial sinusitis, also called bacterial rhinosinusitis or "sinus infection," has symptoms much like viral rhinosinusitis but a different treatment.

Any sinusitis usually begins with common cold viruses. Sometimes a secondary bacterial infection takes hold. Like cold viruses, these bacteria can be inhaled after an infected person coughs or sneezes.

Anyone with viral sinusitis, upper-respiratory allergy, nasal passage abnormality, lung illness, or a weakened immune system is more prone to bacterial sinusitis.

Symptoms include thick yellowish or greenish nasal discharge; one-sided pain in the upper jaw or teeth; one-sided sinus pain and pressure; fatigue; fever; and symptoms that get worse after first improving.

See a doctor right away for severe headache, high fever, stiff neck, or vision changes. These can indicate a medical emergency.

Diagnosis is made with a simple examination in the doctor's office.

Bacterial sinusitis can be treated with antibiotics, but this is not always necessary.

Often rest, fluids, and over-the-counter pain relievers and decongestants are enough.

Prevention is done through good lifestyle and hygiene to keep the immune system strong.

One-sided nose swelling treatments and relief

Treating one-sided nose swelling is possible at home. However, if you cannot find relief, you should consult your physician for further medical treatment.

At-hometreatments

Treatments you can try at home include:

  • Warm and cold compresses: These can help reduce pain and swelling if your one-sided nose swelling is due to an infectious cause or trauma.
  • Over-the-counter pain medications: Pain medications such as the NSAIDs ibuprofen (Advil, Motrin), naproxen (Naproxen) and aspirin can help reduce pain, swelling, and redness because they work by reducing inflammation in your body. Acetaminophen (Tylenol) can also help with pain and fever but does not treat inflammation.
  • Nasal decongestants: When your nose feels stuffy either from a cold or from allergies, over-the-counter nasal decongestants like pseudoephedrine (Sudafed) and Vicks Sinex can shrink the swollen blood vessels and tissues causing your stuffiness.Another class of medicines that can help in reducing nasal congestion are nasal sprays with corticosteroids such as Flonase.
  • Antihistamines: If your nasal congestion and nose swelling are due to allergies,antihistamines like Allegra, Claritin, Zyrtec, and Benadryl can calm the inflammation.
  • Irrigation: If your nasal swelling is caused by infection or allergy, liquid solutions made with saline (salt-water) can rinse away the bacteria, fungus, or irritants causing your body's reaction. Nasal irrigation kits can be bought over-the-counter, and when used as directed, they can help to decrease symptoms of congestion and nasal discharge, pain, or pressure.

Medical treatments

If conservative measures do not work and you are still suffering from symptoms of nose swelling, you should consult your physician. They may recommend:

  • Incision and drainage: If your nasal swelling is caused by a skin infection that has led to a collection of pus under your skin, a medical professional may need to cut a small hole (incision) in the skin overlying the bump in order to drain the pus collection.
  • Antibiotics or antifungals: You may also be prescribed medication in the form of a pill or cream/ointment in order to fight the infection if your nose-swelling is due to a bacterial or fungal cause.
  • Steroids and other anti-inflammatory medications: If your nose-swelling is due to an autoimmune or inflammatory disease, a medical professional may recommend steroids or other medicines that work by calming down your body's overstimulated immune system, so it is less likely to attack your healthy cells.
  • Surgery: If your nose swelling is due to an infection in your nose or sinuses that does not respond to treatment with medicines, your physician may recommend surgery to clear out the infection and make it easier for medicine to reach all areas of your nose. If your noseswelling is due to trauma that has caused damage or distortion to the bone or cartilage in your nose, you mayneed surgery to fix the damage and get your bones back into their natural position. You may also need surgery if your nose swelling is due to abnormal cell growth during which a medical doctor will remove the abnormal growth(s), assess what kind of cells are causing the growth(s), and whether they are cancerous or not.

FAQs about one-sided nose swelling

Here are some frequently asked questions about one-sided nose swelling.

Why can't I smell when I have a cold or nose swelling?

The nerves that are responsible for your sense of smell are found high up in your nose. Anything that interferes with the ability of a molecule that carries scent to travel into your nose and up to where the nerves live can lead to a decreased sense of smell. This is why when you have nasal congestion due to infectious or allergic causes, or a physical blockage due to an abnormal growth, you may notice your ability to smell decreases or goes away completely.

Why do I have a decreased ability to taste when I have nasal congestion?

Your sense of smell is also tied to your ability to taste. Without the sense of smell your taste buds don't work as well, so you may find you enjoy food less during a cold or when you have some other reason for any nasal blockage.

What causes nasal polyps?

Nasal polyps are small, non-cancerous growths in the nasal cavity or the sinuses. They can block the nasal passage leading to a decreased ability to breathe, can interfere with the ability to smell, and can also encourage bacterial or fungal infection by interfering with the body's natural methods of clearing irritants and pathogens that are everywhere in the environment. They are often associated with allergies and asthma but we still don't know exactly what causes them.

How can nasal polyps be treated?

This depends, as nasal polyps can grow and shrink over time. Since they are non-cancerous, they do not necessitate removal unless they are impeding your quality of life. Treatment with oral or nasal steroids can help shrink polyps but they sometimes require surgery for complete removal.

Why do allergies cause my nose to swell?

Allergies can cause nasal swelling because your body's reaction to an allergy-causing material is to alert your immune system to activate cells that fight whatever is causing the allergy. These cells release substances, including histamine, that aim to fight the offending material; however, this also leads to swelling of the nasal lining and opening of the blood vessels which causes redness. Since this reaction occurs due to the body's production of substances like histamine, antihistamines like Allegra, Claritin, Zyrtec, and Benadryl work to reduce the response when it occurs because of generally harmless particles like plant pollen, molds, and animal hairs.

Nasal blockage and unpleasant taste and smellPosted April 26, 2021 by G.
My nose has been blocked for over 3 months now, and 2 weeks back I started to develop this weird sense of taste and smell. When I check inside my blocked nose, it's swollen, and that is why I can't breathe through my nose. I tried home remedies, but they are not helping. I use nasal sprays for temporary relief, but once the dose is over, the congestion comes again. I really need to see a doctor but I have no money.
