9 causes of a nose itch
This list does not constitute medical advice and may not accurately represent what you have.
New-onset seasonal allergies
New-onset seasonal allergies, also called adult-onset seasonal allergies, are sensitivities to pollen, mold, and other irritants that cause nasal congestion, runny nose, sneezing, itchy eyes, and sore throat.
Seasonal allergies commonly begin in childhood but can start at any age, especially among those with a family history. Moving to a different geographic location may trigger the allergy in someone with a genetic predisposition. Anyone with asthma is more likely to experience adult-onset seasonal allergies.
Sometimes the symptoms are actually from "pregnancy rhinitis" – nasal congestion and sneezing due to the effects of pregnancy hormones on the nasal tissue.
A new-onset allergy is often thought to be a cold, but a cold will clear up without treatment. Allergies persist, never getting better or worse, and can interfere with quality of life.
Diagnosis is made by an allergist, who will use skin tests and blood tests.
There is no cure for seasonal allergies but the symptoms can be managed for greater comfort and relief. Antihistamines, corticosteroid nasal sprays, and immunotherapy or "allergy shots" can be very effective.
Top Symptoms: sore throat, congestion, cough with dry or watery sputum, mucous dripping in the back of the throat, fatigue
Symptoms that never occur with new-onset seasonal allergies: fever, yellow-green runny nose, chills, muscle aches
Rhinitis simply means "inflammation of the nose." When it is caused by something other than allergies, it is called vasomotor rhinitis. "Vasomotor" simply refers to the constriction or dilation of blood vessels.
Different substances can trigger the vasomotor reaction, even though it is not an allergic reaction. Common causes are certain medications; air pollution; and chronic medical conditions.
Symptoms include runny nose, sneezing, congestion, and postnasal drip. Since no allergy is involved, there will not be the scratchy throat or itchy eyes and nose of allergic rhinitis.
A medical provider should be seen for ongoing symptoms, since they can interfere with quality of life. Also, using over-the-counter medications meant for allergic rhinitis will not help in a case of vasomotor rhinitis.
Diagnosis is made through patient history, physical examination, and allergy tests, in order to rule out allergies as a cause of the symptoms.
Treatment involves using the appropriate medications to ease the symptoms, and avoiding any triggers as much as possible.
Top Symptoms: congestion, mucous dripping in the back of the throat, runny nose, frequent sneezing, eye itch
Symptoms that never occur with non-allergic rhinitis: fever, sinus pain, facial fullness or pressure
Allergic contact dermatitis of the nose
Allergic contact dermatitis is a condition in which the skin becomes irritated and inflamed following physical contact with an allergen. Common products known to cause allergic dermatitis include plants, metals, soap, fragrance, and cosmetics.
Top Symptoms: nose itch, nose redness, scabbed area of the nose
Symptoms that always occur with allergic contact dermatitis of the nose: nose redness
Dermatofibroma of the nose
Dermatofibroma (superficial benign fibrous histiocytoma) is a common cutaneous nodule of unknown etiology that occurs more often in women. Dermatofibroma frequently develops on the extremities (mostly the lower legs) and is usually asymptomatic, although pruritus and tenderness can be present
Top Symptoms: nose itch, small nose lump, skin-colored nose bump, pink or red nose bump, marble-size nose lump
Urgency: Wait and watch
Allergies are an overreaction by the immune system to something that does not bother most other people. Many people who have allergies are sensitive to pollen, but other things such as dust mites, animal dander, cockroaches, and mold can also cause a reaction.
Top Symptoms: fatigue, irritability, trouble sleeping, runny nose, congestion
Symptoms that never occur with chronic allergies: fever, yellow-green runny nose, chills, muscle aches
Non-specific insect bite
Insect bites are very common. The saliva given off during the bit can sometimes cause dangerous allergic reactions that affect your ability to breathe. However, the vast majority of insect bites have no adverse effects besides the inflammation where the bite occurred.
Mosquito bites are bites from flying insects that feed on the blood of animals, including humans. Mosquito bites are more common during the summer or in warmer climates, at dawn or dusk, and near bodies of water.
In most cases, mosquito bites will cause a local skin reaction that gets better on ..
Normal episode of itchy skin
Itchy skin is also called pruritis. There are a number of "normal" causes for itching, meaning the cause is not disease-related and does not result in seriously damaged skin.
The most common causes are:
- Dry skin, due to bathing in soap or bubble bath that may be too harsh and is stripping the natural oils from the skin.
- Mild allergies, which may be caused by dust; certain plants and flowers; nickel-containing jewelry; and any sort of soap, detergent, lotion, or perfume.
- Pregnancy, due to stretching of skin or to a condition called prurigo. Prurigo causes small, itchy bumps which may be due to an autoimmune system dysfunction during pregnancy.
Menopause, due to hormonal changes that may leave the skin overly dry.
Diagnosis is made through physical examination and sometimes allergy tests.
Treatment involves bathing only with mild, hypoallergenic soap; regular moisturizing with unscented lotion; wearing soft, loose, non-synthetic clothing; avoiding any substances that seem to provoke the itching; and sometimes prescription medicated creams.
Top Symptoms: feeling itchy or tingling all over
Symptoms that always occur with normal episode of itchy skin: feeling itchy or tingling all over
Eczema (atopic dermatitis) is a non-contagious chronic skin condition that produces an itchy rash. It is caused by a genetic condition that affects the skin's ability to protect itself from bacteria and allergens. The most susceptible are those with a family hi..
