Differential Diagnosis for 35 yo Female with Runny Nose, Watery Eyes, and Sneezing
- Single Most Likely Diagnosis
- Allergic Rhinitis: This is the most likely diagnosis given the symptoms of runny nose, watery eyes, and sneezing, which are classic for allergic reactions. The presence of swollen nasal turbinates and mild swelling and erythema of the conjunctiva further supports this diagnosis, as these are common findings in allergic rhinitis. Common triggers include pollen, dust mites, pet dander, and mold.
- Other Likely Diagnoses
- Viral Upper Respiratory Infection (URI): Although the duration of symptoms (1 month) is somewhat prolonged for a typical URI, some viral infections can cause persistent symptoms. However, the lack of systemic symptoms such as fever and the specific pattern of nasal and conjunctival involvement make this less likely than allergic rhinitis.
- Non-Allergic Rhinitis: This condition presents with similar symptoms to allergic rhinitis but without an identifiable allergic trigger. It can be caused by various factors, including environmental irritants, hormonal changes, or certain medications.
- Do Not Miss Diagnoses
- Sinusitis: While less likely given the absence of specific symptoms such as facial pain or purulent discharge, sinusitis can present with similar nasal symptoms and must be considered, especially if there's a history of recurrent infections or if symptoms worsen over time.
- Vasculitis (e.g., Granulomatosis with Polyangiitis): Although rare, vasculitis can cause a wide range of symptoms including those similar to allergic rhinitis, along with more systemic symptoms. It's crucial to consider this in the differential due to its potential severity and the need for early treatment.
- Rare Diagnoses
- Sjögren's Syndrome: An autoimmune disorder that can cause dry eyes and dry mouth but may also present with nasal symptoms due to inflammation. It's less likely but should be considered in patients with persistent symptoms and systemic complaints.
- Mastocytosis: A condition characterized by an accumulation of mast cells in one or more organs, which can lead to a variety of symptoms including allergic-like reactions. It's rare and usually presents with additional symptoms such as skin lesions or gastrointestinal complaints.
