Differential Diagnosis for Nausea, Body Aches, and Cough
Single Most Likely Diagnosis
- Viral Upper Respiratory Infection (URI): This is the most common cause of the symptoms described, including nausea, body aches, and cough, due to the high prevalence of viral infections such as the common cold or influenza.
Other Likely Diagnoses
- Influenza: Similar to URI but often presents with more severe symptoms including high fever, significant body aches, and can lead to complications like pneumonia.
- Bronchitis: An inflammation of the bronchial tubes, often caused by a virus, which can lead to a persistent cough and may be accompanied by body aches and nausea.
- Pneumonia: An infection of the lungs that can be caused by bacteria, viruses, or fungi, presenting with cough, fever, body aches, and potentially nausea.
Do Not Miss Diagnoses
- Pulmonary Embolism: Although less common, it's critical to consider due to its high mortality rate. Symptoms can include sudden onset of cough, chest pain, and possibly nausea, though body aches might not be as prominent.
- Sepsis: A life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. Early symptoms can be non-specific, including nausea, body aches, and cough, especially if the infection is respiratory in origin.
- COVID-19: Given its global impact and variability in presentation, COVID-19 should be considered, especially if there's a history of exposure or travel. Symptoms can range from mild to severe and include cough, body aches, and nausea.
Rare Diagnoses
- Lymphoma: Certain types of lymphoma can present with systemic symptoms such as fever, night sweats, weight loss, and possibly nausea and body aches. A cough could be present if there's involvement of the lungs or mediastinum.
- Tuberculosis (TB): A bacterial infection that primarily affects the lungs but can spread to other parts of the body. Symptoms can include a chronic cough, fever, night sweats, weight loss, and possibly body aches and nausea.
- Sarcoidosis: An inflammatory disease that can affect multiple organs in the body, including the lungs, and present with a variety of symptoms including cough, fever, and body aches, though it's less likely to cause nausea as a primary symptom.
