Differential Diagnosis for Chronic Sore Throat with Scratchy Eyes
- Single Most Likely Diagnosis
- Allergic Rhinitis: This condition is characterized by chronic inflammation of the nasal passages, often leading to symptoms such as sore throat, scratchy eyes, and nasal congestion. The chronic nature of the symptoms and the combination of sore throat with scratchy eyes make allergic rhinitis a highly plausible diagnosis.
- Other Likely Diagnoses
- Dry Eye Syndrome: This condition can cause scratchy eyes and, if severe, may also lead to throat discomfort due to decreased tear production and potential postnasal drip.
- Viral Pharyngitis: Chronic viral infections can cause persistent sore throat, and some viruses may also cause conjunctivitis, leading to scratchy eyes.
- Sinusitis: Chronic sinus infections can lead to postnasal drip, which may irritate the throat and cause soreness, as well as contribute to eye irritation.
- Do Not Miss Diagnoses
- Granulomatosis with Polyangiitis (GPA): A systemic vasculitis that can affect the respiratory tract and eyes, leading to chronic sore throat and eye symptoms. Although rare, missing this diagnosis could have severe consequences.
- Sjögren's Syndrome: An autoimmune disorder that primarily affects the glands that produce tears and saliva, leading to dry eyes and mouth, which could cause a sore throat.
- Lymphoma: Certain types of lymphoma can present with chronic sore throat and eye symptoms due to involvement of the lymph nodes in the neck and orbits.
- Rare Diagnoses
- Sarcoidosis: A condition characterized by the growth of granulomas in various parts of the body, which can include the lungs, eyes, and lymph nodes, potentially causing chronic sore throat and eye symptoms.
- Relapsing Polychondritis: A rare autoimmune disorder that can cause inflammation of the cartilage in the nose, ears, and trachea, potentially leading to chronic sore throat and eye irritation.
