Dental infection or abscess: The presence of a harder lymph node near the tooth suggests a possible dental infection or abscess, which is a common cause of lymphadenopathy in the facial region. The softer lymph node closer to the nose could be reactive lymphadenopathy in response to the infection.

Viral upper respiratory infection: The patient's symptoms could be related to a viral upper respiratory infection, such as a cold or sinusitis, which can cause lymphadenopathy in the facial region.
Reactive lymphadenopathy: The lymph nodes could be reacting to a non-specific stimulus, such as a minor infection or inflammation in the face.
Allergic reaction or sinusitis: Allergic reactions or sinusitis can cause lymphadenopathy in the facial region, especially if the patient has a history of allergies or sinus problems.

Lymphoma: Although less likely, lymphoma is a potentially life-threatening condition that can present with lymphadenopathy in the facial region. It is essential to consider this diagnosis to ensure prompt evaluation and treatment if necessary.
Metastatic cancer: Cancer that has spread to the lymph nodes in the face, such as from a primary tumor in the head and neck region, is another critical diagnosis that should not be missed.
Tuberculosis or other granulomatous disease: Tuberculosis or other granulomatous diseases, such as sarcoidosis, can cause lymphadenopathy in the facial region and require prompt diagnosis and treatment.

Kawasaki disease: This rare condition, which primarily affects children, can cause lymphadenopathy, fever, and other symptoms.
Kimura disease: A rare, chronic inflammatory disorder that can cause lymphadenopathy and other symptoms, primarily in Asian males.
Castleman disease: A rare disorder that can cause lymphadenopathy, fever, and other symptoms, often in the facial region.
