Differential Diagnosis for Vertigo, Vomiting, Chills, and Relief with Sleep
Single Most Likely Diagnosis
- Benign Paroxysmal Positional Vertigo (BPPV): This condition is characterized by brief, intense episodes of vertigo triggered by specific head movements, which can be accompanied by nausea and vomiting. The symptoms can be relieved by rest or sleep, and the short duration of symptoms (last 3 hours) fits within the timeframe often seen in BPPV episodes.
Other Likely Diagnoses
- Vestibular Migraine: This condition can cause vertigo, nausea, vomiting, and sensitivity to light and sound. While migraines are typically associated with headaches, some individuals may experience vertigo without headache. The relief with sleep could be due to the natural fluctuation in migraine symptoms.
- Labyrinthitis: An inner ear disorder characterized by inflammation of the labyrinth, which can cause vertigo, hearing loss, and sometimes nausea and vomiting. The symptoms can fluctuate and may improve with rest.
Do Not Miss Diagnoses
- Stroke or Transient Ischemic Attack (TIA): Although less common, vertigo can be a symptom of a stroke or TIA, especially if accompanied by other neurological deficits. It's crucial to rule out these conditions due to their high morbidity and mortality.
- Meningitis: Inflammation of the protective membranes covering the brain and spinal cord, which can cause vertigo, vomiting, chills, and fever. The severity and potential for serious complications make it a "do not miss" diagnosis.
- Acute Otitis Media or Mastoiditis: Infections of the middle ear or mastoid bone can cause vertigo, fever, and vomiting. While less likely, these conditions require prompt treatment to prevent complications.
Rare Diagnoses
- Multiple Sclerosis (MS): An autoimmune disease that can affect various parts of the brain and spinal cord, leading to a wide range of symptoms, including vertigo. However, MS is less likely given the acute onset and relief with sleep.
- Mal de Debarquement Syndrome: A rare condition characterized by vertigo and imbalance after a journey by boat, plane, or other vehicle. The symptoms can persist for hours or even days after the trip and may improve with sleep, but this diagnosis would require a relevant travel history.
