Nasal vestibulitis is the diffuse dermatitis of nasal vestibule. It is often caused by "Staphylococcus aureus." It may be secondary to chronic rhinorrhea, nose picking or viral infections. In acute vestibulitis, the skin is red, swollen and tender. In chronic vestibulitis, induration of vestibular skin and crusting is seen. It is treated by cleaning the nasal vestibule of all crusts with a cotton applicator soaked in hydrogen peroxide. Antibiotic steroid ointment is sometimes helpful. Chronic fissures are treated by cautery.

VVS is characterized by severe pain with attempted penetration of the vaginal orifice and complaints of tenderness with pressure within the vulval vestibule. Usually there are no reports of pain with pressure to other surrounding areas of the vulva. The feelings of irritation and burning can persist for hours or days following sexual activity, engendering a sense of hopelessness and depression. VVS also can often cause dyspareunia.

The pain may be provoked by contact with an object, such as with the insertion of a tampon or penis or with the pressure from sitting on a bicycle seat, "provoked vestibulodynia", or it may be constant, as in the case of unprovoked, generalized vestibulodynia. Some women have had pain since their first penetration (primary vulvar vestibulitis) while some have had it after a period of time with pain-free penetration (secondary vulvar vestibulitis).

Relationship problems often occur as the result of chronic frustration, disappointment, and depression associated with the condition.

Acute adenoiditis is characterized by fever, runny nose, nasal airway obstruction resulting in predominantly oral breathing, snoring and sleep apnea, Rhinorrhea with serous secretion in viral forms and mucous-purulent secretion in bacterial forms. In cases due to viral infection symptoms usually recede spontaneously after 48 hours, symptoms of bacterial adenoiditis typically persist up to a week. Adenoiditis is sometimes accompanied by tonsillitis. Repeated adenoiditis may lead to enlarged adenoids.

Adenoiditis is the inflammation of the adenoid tissue, usually caused by an infection. Adenoiditis is treated using medication (antibiotics and/or steroids) or surgical intervention.

Adenoiditis may produce cold-like symptoms. However, adenoiditis symptoms often persist for ten or more days, and often include pus-like discharge from nose.

The infection cause is usually viral. However, if the adenoiditis is caused by a bacterial infection, antibiotics may be prescribed for treatment. A steroidal nasal spray may also be prescribed in order to reduce nasal congestion. Severe or recurring adenoiditis may require surgical removal of the adenoids (adenotonsillectomy).

Diagnosis is readily made by the cotton-swab test, in which pressure is applied in a circular fashion around the vulvar vestibule to assess complaints of pain. Laboratory tests are used to exclude bacterial or viral infection, and a careful examination of the vulvo/vaginal area is conducted to assess whether any atrophy is present.

Pain is the most notable symptom of vulvodynia, and can be characterized as a burning, stinging, irritation or sharp pain that occurs in the vulva and entrance to the vagina. It may be constant, intermittent or happen only when the vulva is touched, but vulvodynia is usually defined as lasting for years.

Symptoms may occur in one place or the entire vulvar area. It can occur during or after sexual activity, when tampons are inserted, or when prolonged pressure is applied to the vulva, such as during sitting, bike riding, or horseback riding. Some cases of vulvodynia are idiopathic where no particular cause can be determined.

Rhinoscleroma has been divided into 3 stages: catarrhal/atrophic, granulomatous, and sclerotic stages. The catarrhal stage begins with a nonspecific rhinitis, which progresses into purulent, fetid rhinorrhea, and crusting, which can last for weeks or even months. The granulomatous stage results in the development of a bluish red nasal mucosa and the development of intranasal rubbery nodules or polyps. Nose bleeds, nasal deformity, and destruction of the nasal cartilage are also noted (Hebra nose). The damage may result in anesthesia of the soft palate, enlargement of the uvula, dysphonia, and various degrees of airway obstruction. The fibrotic stage is characterized by sclerosis and fibrosis. Lymphadenitis is absent.

Vulvar vestibulitis syndrome (VVS), vestibulodynia, or simply vulvar vestibulitis or "localized (to the vestibule) provoked vulvodynia" refers to pain localized to the vestibular region. It tends to be associated with a highly localized "burning" or "cutting" type of pain. The pain of vulvodynia may extend into the clitoris; this is referred to as clitorodynia.

Vulvar vestibulitis syndrome is the most common subtype of vulvodynia that affects premenopausal women – the syndrome has been cited as affecting about 10%–15% of women seeking gynecological care.

Sinusitis (or rhinosinusitis) is defined as an inflammation of the mucous membrane that lines the paranasal sinuses and is classified chronologically into several categories:

- Acute rhinosinusitis – A new infection that may last up to four weeks and can be subdivided symptomatically into severe and non-severe. Some use definitions up to 12 weeks.

- Recurrent acute rhinosinusitis – Four or more full episodes of acute sinusitis that occur within one year

- Subacute rhinosinusitis – An infection that lasts between four and 12 weeks, and represents a transition between acute and chronic infection

- Chronic rhinosinusitis – When the signs and symptoms last for more than 12 weeks.

- Acute exacerbation of chronic rhinosinusitis – When the signs and symptoms of chronic rhinosinusitis exacerbate, but return to baseline after treatment

All these types of sinusitis have similar symptoms, and are thus often difficult to distinguish. Acute sinusitis is very common. Roughly ninety percent of adults have had sinusitis at some point in their life.

Headache/facial pain or pressure of a dull, constant, or aching sort over the affected sinuses is common with both acute and chronic stages of sinusitis. This pain is typically localized to the involved sinus and may worsen when the affected person bends over or when lying down. Pain often starts on one side of the head and progresses to both sides.

Acute sinusitis may be accompanied by thick nasal discharge that is usually green in color and may contain pus (purulent) and/or blood. Often a localized headache or toothache is present, and it is these symptoms that distinguish a sinus-related headache from other types of headaches, such as tension and migraine headaches. Another way to distinguish between toothache and sinusitis is that the pain in sinusitis is usually worsened by tilting the head forwards and with valsalva maneuvers.

Infection of the eye socket is possible, which may result in the loss of sight and is accompanied by fever and severe illness. Another possible complication is the infection of the bones (osteomyelitis) of the forehead and other facial bones – Pott's puffy tumor.

Sinus infections can also cause middle ear problems due to the congestion of the nasal passages. This can be demonstrated by dizziness, "a pressurized or heavy head", or vibrating sensations in the head. Post-nasal drip is also a symptom of chronic rhinosinusitis.

Halitosis (bad breath) is often stated to be a symptom of chronic rhinosinusitis; however, gold standard breath analysis techniques have not been applied. Theoretically, there are several possible mechanisms of both objective and subjective halitosis that may be involved.

A 2004 study suggested that up to 90% of "sinus headaches" are actually migraines. The confusion occurs in part because migraine involves activation of the trigeminal nerves, which innervate both the sinus region and the meninges surrounding the brain. As a result, it is difficult to accurately determine the site from which the pain originates. People with migraines do not typically have the thick nasal discharge that is a common symptom of a sinus infection.

A positive culture in MacConkey agar is diagnostic, but cultures are only positive in 50–60% of cases. Diagnostic characteristics are most commonly found in the granulomatous stage and are described as being chronic inflammatory cells, Russell bodies, and pseudoepitheliomatous hyperplasia, and groups of large vacuolated histiocytes containing "Klebsiella rhinoscleromatis" (Mikulicz cells).

Permanent loss of smell and impairment of taste may also be a result of this disease, even after the symptoms are cured.

The characteristic presentation of RM involves nasal congestion without rhinorrhea, postnasal drip, or sneezing following several days of decongestant use. This condition typically occurs after 5–7 days of use of topical decongestants. Patients often try increasing both the dose and the frequency of nasal sprays upon the onset of RM, worsening the condition. The swelling of the nasal passages caused by rebound congestion may eventually result in permanent turbinate hyperplasia, which may block nasal breathing until surgically removed.

Chronic atrophic rhinitis is a chronic inflammation of nose characterised by atrophy of nasal mucosa, including the glands, turbinate bones and the nerve elements supplying the nose. Chronic atrophic rhinitis may be primary and secondary. Special forms of chronic atrophic rhinitis are rhinitis sicca anterior and ozaena.

A URI may be classified by the area inflamed.

Rhinitis affects the nasal mucosa, while rhinosinusitis or sinusitis affects the nose and paranasal sinuses, including frontal, ethmoid, maxillary, and sphenoid sinuses. Nasopharyngitis (rhinopharyngitis or the common cold) affects the nares, pharynx, hypopharynx, uvula, and tonsils generally. Without involving the nose, pharyngitis inflames the pharynx, hypopharynx, uvula, and tonsils. Similarly, epiglottitis (supraglottitis) inflames the superior portion of the larynx and supraglottic area; laryngitis is in the larynx; laryngotracheitis is in the larynx, trachea, and subglottic area; and tracheitis is in the trachea and subglottic area.

Rhinorrhea is characterized by an excess amount of mucus produced by the mucous membranes that line the nasal cavities. The membranes create mucus faster than it can be processed, causing a backup of mucus in the nasal cavities. As the cavity fills up, it blocks off the air passageway, causing difficulty breathing through the nose. Air caught in nasal cavities, namely the sinus cavities, cannot be released and the resulting pressure may cause a headache or facial pain. If the sinus passage remains blocked, there is a chance that sinusitis may result. If the mucus backs up through the Eustachian tube, it may result in ear pain or an ear infection. Excess mucus accumulating in the throat or back of the nose may cause a post-nasal drip, resulting in a sore throat or coughing. Additional symptoms include sneezing, nosebleeds, and nasal discharge.

Rhinorrhea or rhinorrhoea is a condition where the nasal cavity is filled with a significant amount of mucus fluid. The condition, commonly known as a runny nose, occurs relatively frequently. Rhinorrhea is a common symptom of allergies (hay fever) or certain diseases, such as the common cold. It can be a side effect of crying, exposure to cold temperatures, cocaine abuse or withdrawal, such as from opioids like methadone. Treatment for rhinorrhea is not usually necessary, but there are a number of medical treatments and preventive techniques available.

The term was coined in 1866 and is a combination of the Greek terms "rhino-" ("of the nose") and "-rhoia" ("discharge" or "flow").

In uncomplicated colds, cough and nasal discharge may persist for 14 days or more even after other symptoms have resolved.

Acute upper respiratory tract infections include rhinitis, pharyngitis/tonsillitis and laryngitis often referred to as a common cold, and their complications: sinusitis, ear infection and sometimes bronchitis (though bronchi are generally classified as part of the lower respiratory tract.) Symptoms of URTIs commonly include cough, sore throat, runny nose, nasal congestion, headache, low-grade fever, facial pressure and sneezing.

Symptoms of rhinovirus in children usually begin 1–3 days after exposure. The illness usually lasts 7–10 more days.

Color or consistency changes in mucous discharge to yellow, thick, or green are the natural course of viral upper respiratory tract infection and not an indication for antibiotics.

Group A beta hemolytic streptococcal pharyngitis/tonsillitis (strep throat) typically presents with a sudden onset of sore throat, pain with swallowing and fever. Strep throat does not usually cause runny nose, voice changes, or cough.

Pain and pressure of the ear caused by a middle ear infection (otitis media) and the reddening of the eye caused by viral conjunctivitis are often associated with upper respiratory infections.

Initial signs of FVR include coughing, sneezing, nasal discharge, conjunctivitis, and sometimes fever (up to 106) and loss of appetite. These usually resolve within four to seven days, but secondary bacterial infections can cause the persistence of clinical signs for weeks. Frontal sinusitis and empyema can also result.

FHV-1 also has a predilection for corneal epithelium, resulting in corneal ulcers, often pinpoint or dendritic in shape. Other ocular signs of FHV-1 infection include conjunctivitis, keratitis, keratoconjunctivitis sicca (decreased tear production), and corneal sequestra. Infection of the nasolacrimal duct can result in chronic epiphora (excess tearing). Ulcerative skin disease can also result from FHV-1 infection. FHV-1 can also cause abortion in pregnant queens, usually at the sixth week of gestation, although this may be due to systemic effects of the infection rather than the virus directly.

In chronic nasal and sinus disease of cats, FHV-1 may play more of an initiating role than an ongoing cause. Infection at an early age may permanently damage nasal and sinus tissue, causing a disruption of ciliary clearance of mucus and bacteria, and predispose these cats to chronic bacterial infections.

Rhinitis medicamentosa (or RM) is a condition of rebound nasal congestion brought on by extended use of topical decongestants (e.g., oxymetazoline, phenylephrine, xylometazoline, and naphazoline nasal sprays) and certain oral medications (e.g., sympathomimetic amines and various 2-imidazolines) that constrict blood vessels in the lining of the nose.

Labial fusion is never present at birth, but rather acquired later in infancy, since it is caused by insufficient estrogen exposure and newborns have been exposed to maternal estrogen "in utero". It typically presents in infants at least 3 months old. Most presentations are asymptomatic and are discovered by a parent or during routine medical examination. In other cases, patients may present with associated symptoms of dysuria, urinary frequency, refusal to urinate, or post-void dribbling. Some patients present with vaginal discharge due to pooling of urine in the vulval vestibule or vagina.

Feline viral rhinotracheitis (FVR) is an upper respiratory or pulmonary infection of cats caused by "feline herpesvirus 1", of the family "Herpesviridae". It is also commonly referred to as feline influenza, feline coryza, and feline pneumonia but, as these terms describe other very distinct collections of respiratory symptoms, they are misnomers for the condition. Viral respiratory diseases in cats can be serious, especially in catteries and kennels. Causing one-half of the respiratory diseases in cats, FVR is the most important of these diseases and is found worldwide. The other important cause of feline respiratory disease is "feline calicivirus".

FVR is very contagious and can cause severe disease, including death from pneumonia in young kittens. It can cause flat-chested kitten syndrome, but most evidence for this is anecdotal. All members of the "Felidae" family are susceptible to FVR; in fact, FHV-1 has caused a fatal encephalitis in lions in Germany.

Paroxysmal sneezing in morning, especially in morning while getting out of the bed. Excessive rhinorrhea - watering discharge from the nose when patient bends forward. Nasal obstruction - bilateral nasal stuffiness alternates from one site to other; this is more marked at night, when the dependent side of nose is often blocked. Postnasal drip.

Nasal congestion is the blockage of the nasal passages usually due to membranes lining the nose becoming swollen from inflamed blood vessels.

Nasal decongestants target the discomfort directly. These come as nasal sprays, inhalers, and as oral pills.

Nasal congestion has many causes and can range from a mild annoyance to a life-threatening condition. Most people prefer to breathe through the nose (historically referred to as "obligate nasal breathers"). Nasal congestion in an infant in the first few months of life can interfere with breastfeeding and cause life-threatening respiratory distress; in older children and adolescents it is often just an annoyance but can cause other difficulties.

Nasal congestion can interfere with the hearing and speech. Significant congestion may interfere with sleep, cause snoring, and can be associated with sleep apnea. In children, nasal congestion from enlarged adenoids has caused chronic sleep apnea with insufficient oxygen levels and hypoxia, as well as right-sided heart failure. The problem usually resolves after surgery to remove the adenoids and tonsils, however the problem often relapses later in life due to craniofacial alterations from chronic nasal congestion.

Nasal congestion can also cause mild facial and head pain, and a degree of discomfort, often from allergies or the common cold.

The condition can be diagnosed based on inspection of the vulva. In patients with labial fusion, a flat plane of tissue with a dense central line of tissue is usually seen when the labia majora are retracted, while an anterior opening is usually present below the clitoris.
