TL;DR: Brief spinning when you roll over in bed, lie down, or tip your head back is the classic sign of BPPV — a common, very treatable inner-ear problem. A physiotherapist can usually resolve it in one to three visits with a simple repositioning manoeuvre.
Direct answer: Short, intense spinning triggered by a change in head position — rolling over in bed, lying down, looking up — is the hallmark of BPPV (benign paroxysmal positional vertigo). It happens when tiny crystals in the inner ear move into the wrong canal. It is one of the most common and most treatable causes of vertigo: a vestibular physiotherapist confirms which ear is affected and uses a repositioning manoeuvre (such as the Epley) that often resolves it in one to three sessions.
What does BPPV feel like?
The pattern is distinctive, which is good news — it’s one of the easier types of dizziness to identify.
- The spinning is brief but intense — usually seconds to under a minute, not constant.
- It’s triggered by a change in head position, not by standing still. Classic triggers: rolling over in bed, lying down, sitting up, tipping your head back (looking up at a shelf), or bending forward.
- Between episodes you may feel completely normal, or a bit unsteady and “off.”
- It can come with nausea, and it often arrives out of nowhere — many people first notice it when they roll over in bed one morning.
If your dizziness is constant rather than position-triggered, or comes with headache, weakness, slurred speech, or hearing loss, that points somewhere other than BPPV — and some of those are red flags (see below).
The typical episode length I’ve seen in my patients is 10–30 seconds, definitely less than a minute. The most common triggers I’ve seen in my patients are rolling over in bed or getting out of bed. The next most common would be tilting the head back to look up at something like a shelf.
Why does it happen?
Your inner ear contains tiny calcium-carbonate crystals that normally sit in one part of the balance organ, helping you sense gravity and movement. In BPPV, some of these crystals break loose and drift into one of the semicircular canals where they don’t belong.
Now, when you move your head, the loose crystals slosh the fluid in that canal and fire a false “you’re spinning” signal to your brain — even though you only rolled over. That mismatch is the vertigo.
It often has no obvious cause. It becomes more common with age, and it can follow a head injury, an inner-ear infection, or a long period lying flat. When dizziness starts after a blow to the head, it is worth having the concussion itself assessed as well — our concussion management programme and this guide on when to see a physiotherapist after a concussion cover that side of it.
How to stop the dizziness: the fix is mechanical
Here’s what surprises most people — BPPV usually isn’t treated with medication or “waiting it out.” It’s treated by physically moving the crystals back where they belong.
A vestibular physiotherapist does two things:
- Confirms it’s BPPV and which ear. A positional test (the Dix-Hallpike) provokes the vertigo briefly while the physiotherapist watches your eye movements — the eyes give away exactly which canal the crystals are in.
- Performs a repositioning manoeuvre. The most widely known is the Epley manoeuvre: a specific sequence of head and body positions that guides the crystals out of the canal and back to where they cause no symptoms. It takes a few minutes.
Many people walk out noticeably better the same day, and most cases resolve in one to three sessions.
Fortunately, the various treatment techniques for BPPV are usually very successful. Many studies have demonstrated success rates of over 80% with one treatment. I would say this figure is consistent with my clinical experience, and the large majority of cases do resolve in one to three sessions.
This is the core of what vestibular rehabilitation does at Envision. For the full picture of what that retraining involves, read what is vestibular rehabilitation?
Can I just do the Epley manoeuvre myself from a video?
It’s tempting — and it sometimes helps — but there are two real catches.
- It has to match the affected ear and canal. Done on the wrong side, it won’t work and can move the crystals into a worse position. The positional test exists precisely to get this right.
- Not all positional dizziness is BPPV. If you self-treat a different problem with an Epley, you delay the right treatment.
A single assessment confirms the diagnosis and the correct side — after which, if it recurs, your physiotherapist can teach you a home version safely. That’s the right order: assessment first, home self-management second.
When dizziness is NOT just BPPV — red flags
Go to a physician or emergency department instead of booking physiotherapy if your dizziness comes with any of:
- Sudden severe headache, the “worst headache of your life”
- Weakness, numbness, or drooping on one side of the face or body
- Slurred speech or trouble understanding speech
- Double vision or sudden vision loss
- New hearing loss or ringing in one ear
- Dizziness that is constant and unrelenting rather than triggered by movement
These point to causes that need medical assessment first. For position-triggered spinning without these features, BPPV is the likely answer and vestibular physiotherapy is the fix.
FAQ
How do I know if my dizziness is BPPV?
The tell is that it’s brief (seconds to a minute), intense, and triggered by head-position changes — rolling over in bed, lying down, looking up — rather than constant. A physiotherapist confirms it with a simple positional test.
Will BPPV go away on its own?
It sometimes does over weeks to months, but there’s usually no reason to wait — a repositioning manoeuvre often resolves it in a single visit, and untreated vertigo raises your risk of a fall in the meantime.
Is the Epley manoeuvre safe?
Yes, when it’s matched to the correct ear after a proper assessment. Done for the wrong side or the wrong type of dizziness it can worsen symptoms, which is why a one-time assessment is worth it before relying on it at home.
Do I need a referral to be treated for vertigo in BC?
No. You can book a vestibular physiotherapy assessment directly — the same as for any physiotherapy appointment, as we explain in do I need a referral to see a physiotherapist in BC. If your dizziness came with any red-flag symptoms above, see a physician or emergency department first.
