What should you know about flu vertigo?

Vertigo is the feeling that you or your surroundings are moving when they are not. A flu-like illness can make you light-headed, especially when you stand, but a distinct spinning sensation, vomiting, hearing change, or symptoms brought on by turning your head deserves closer assessment.

Fever, sweating, poor appetite, and vomiting can reduce the fluid available to your circulation. That can produce light-headedness and unsteadiness. Tiredness and muscle aches may also make walking feel unsafe. Nasal congestion can create pressure around the middle ear, which helps the brain interpret movement and position.

A spinning sensation is not proof that influenza is the cause. Other possibilities include benign paroxysmal positional vertigo, Meniere's Disease, Middle Ear Infection, or Migraine. These conditions can occur during or after a viral illness, so the timing alone cannot identify the cause.

Rest, rise slowly, and sit or lie down as soon as spinning begins. Take frequent small sips of fluid if nausea makes drinking difficult, and follow any prescribed flu treatment exactly as directed. Avoid driving, climbing, or operating equipment while your balance is affected. Keep walkways clear and ask someone to stay nearby if you feel at risk of falling.

Make a note of when the sensation started, whether head movement triggers it, and whether you have fever, ear pain, ringing, hearing loss, headache, or vomiting. A clinician may check your ears, eye movements, walking, hydration, and medicines. Do not perform a repositioning exercise such as the Epley Manoeuvre unless a clinician has identified a suitable positional cause and shown you how to do it.

Seek urgent medical help for vertigo with trouble speaking, facial drooping, new weakness or numbness, fainting, severe trouble walking, a sudden severe headache, chest pain, or difficulty breathing. These warning signs need prompt assessment rather than home monitoring.

Arrange medical advice promptly if you cannot keep fluids down, urination becomes much less frequent, symptoms are worsening, fever persists, or vertigo continues after the flu symptoms improve. Ear pain, drainage, new hearing loss, or one-sided ringing also warrants assessment. A clinician can distinguish dehydration or congestion from an inner-ear or neurological problem.

Ask: Does this sound like light-headedness or true vertigo? Could dehydration, an ear problem, migraine, or a medicine be contributing? Which symptoms should send me to urgent care? Is it safe for me to drive, exercise, or use a repositioning manoeuvre?
