Differential Diagnosis for Sore Scratchy Throat and Pain with Swallowing
- Single Most Likely Diagnosis
- Viral Pharyngitis: This is the most common cause of a sore throat and is often accompanied by other symptoms such as cough, runny nose, and fever. The justification for this diagnosis is the high prevalence of viral infections in the general population and the typical presentation of symptoms.
- Other Likely Diagnoses
- Bacterial Pharyngitis (Strep Throat): Caused by Group A beta-hemolytic streptococcus, this condition presents with severe throat pain, fever, and swollen lymph nodes. The justification for including this diagnosis is the potential for serious complications if left untreated, such as rheumatic fever.
- Tonsillitis: Inflammation of the tonsils can cause throat pain and difficulty swallowing. The justification for this diagnosis is the common presentation of tonsillitis with sore throat and the potential for bacterial or viral causes.
- Laryngitis: Inflammation of the larynx (voice box) can cause throat pain and hoarseness. The justification for including this diagnosis is the common presentation of laryngitis with sore throat and voice changes.
- Do Not Miss Diagnoses
- Epiglottitis: A life-threatening condition that causes inflammation of the epiglottis, which can lead to airway obstruction. The justification for including this diagnosis is the potential for rapid progression to respiratory failure if not promptly treated.
- Peritonsillar Abscess: A collection of pus behind the tonsils that can cause severe throat pain and difficulty swallowing. The justification for this diagnosis is the potential for airway obstruction and the need for prompt drainage.
- Retropharyngeal Abscess: A collection of pus in the tissues at the back of the throat, which can cause throat pain and difficulty swallowing. The justification for including this diagnosis is the potential for airway obstruction and the need for prompt drainage.
- Rare Diagnoses
- Lemierre's Syndrome: A rare condition caused by a bacterial infection that can lead to throat pain, fever, and swollen lymph nodes. The justification for including this diagnosis is the potential for serious complications, such as sepsis and thrombophlebitis.
- Diphtheria: A rare bacterial infection that can cause throat pain, fever, and a membrane to form over the tonsils and throat. The justification for including this diagnosis is the potential for serious complications, such as respiratory failure and cardiac problems.
- Oropharyngeal Cancer: A rare condition that can cause throat pain, difficulty swallowing, and a lump in the neck. The justification for including this diagnosis is the potential for serious complications and the need for prompt treatment.
