Differential Diagnosis for Recurrent Sore Throat, Low Grade Fever, Body Aches, Fatigue, and Swollen Neck Glands
Single Most Likely Diagnosis
- Infectious Mononucleosis (Mono): Caused by Epstein-Barr virus (EBV), this condition is characterized by recurrent sore throat, fever, fatigue, and swollen lymph nodes, which matches the patient's symptoms. The recurrence over several months could be due to a prolonged recovery period or repeated exposures.
Other Likely Diagnoses
- Recurrent Pharyngitis: This could be due to bacterial (e.g., Group A beta-hemolytic streptococcus) or viral infections. The frequency of episodes suggests an infectious etiology that is not being fully eradicated or is repeatedly acquired.
- Tonsillitis: Inflammation of the tonsils, which can be caused by both viral and bacterial pathogens, leading to sore throat, fever, and swollen neck glands.
- Allergic Rhinitis: Though primarily associated with nasal symptoms, allergic rhinitis can also cause sore throat and fatigue, especially if postnasal drip is significant.
Do Not Miss Diagnoses
- Hodgkin Lymphoma: A type of cancer that can present with recurrent infections, fever, night sweats, weight loss, and significantly swollen lymph nodes. It's crucial to consider this diagnosis due to its severe implications and the need for early intervention.
- Tuberculosis (TB): Although less common, TB can cause chronic symptoms including fever, fatigue, and swollen lymph nodes. It's a critical diagnosis not to miss due to its public health implications and the need for specific treatment.
- HIV Infection: Individuals with HIV can experience recurrent infections due to their compromised immune system, including sore throats and swollen lymph nodes. Early diagnosis is vital for managing the disease and preventing complications.
Rare Diagnoses
- Cyclic Neutropenia: A rare blood disorder characterized by periodic episodes of neutropenia, which can lead to recurrent infections, including sore throat and fever.
- Periodic Fever Syndromes: A group of disorders that cause recurrent episodes of fever and inflammation, often accompanied by other symptoms like sore throat and fatigue. Examples include Familial Mediterranean Fever and Hyper-IgD syndrome.
- Castleman Disease: A rare disorder that involves an overgrowth of cells in the body's lymph nodes, which can cause fever, fatigue, and swollen lymph nodes, among other symptoms.
