What is the most useful thing to tell the doctor?
How long each episode lasts. Seconds means BPPV; minutes to hours with hearing changes means Ménière's; days of constant severe vertigo means vestibular neuritis. That single answer, plus whether your hearing is affected and what triggers it, sorts out most vertigo.
My vertigo lasts seconds when I roll over in bed.
That is almost certainly BPPV — the commonest cause, and the most satisfying to treat. The Epley manoeuvre resolves it in a single session for most people, sometimes immediately. Ask specifically for it. Tablets do nothing for BPPV and delay recovery.
I've been on prochlorperazine for months. Is that right?
Almost certainly not. These tablets are for a few days of acute severe vertigo with vomiting — no longer. Beyond that they prevent the brain compensating, prolong the dizziness, and cause drowsiness and movement side effects. Long-term use is one of the commonest and most correctable problems here, and stopping them alongside vestibular exercises is often what finally allows improvement.
When is vertigo an emergency?
When it comes with double vision, slurred speech, weakness or numbness, difficulty swallowing, or an inability to walk or sit unsupported. A stroke affecting the balance centres can present as vertigo alone, and those additional features are what distinguish it. Call 999.
Should I rest until it goes?
Only for the first day or two of a severe attack. After that, movement is the treatment — the brain recalibrates only by receiving the signals it is finding confusing. Vestibular rehabilitation exercises deliberately provoke mild dizziness in order to retrain the system, and feeling slightly wobbly while doing them means they are working.
Can I drive?
Not during attacks, and not at all if attacks come without warning. Depending on the cause there may be a legal duty to inform the DVLA — particularly with Ménière's disease or unexplained recurrent vertigo. Worth asking directly rather than assuming, and worth avoiding swimming too, since vertigo underwater is genuinely dangerous.
Could this be migraine if I don't get headaches?
Yes — vestibular migraine frequently occurs without any headache at all, which is exactly why it is missed. Suspect it with vertigo lasting minutes to days, light or sound sensitivity, and a personal or family history of migraine. It responds to migraine treatment, which can be transformative for someone treated for years as an inner ear problem.
Will BPPV come back?
It can, and recurrence is common — but it is not a failure of treatment, and the manoeuvre works again. If you recognise the pattern returning, you do not need to start from scratch; ask for the repositioning treatment directly.
