I’ve been thinking (does anything good ever come after that phrase?), anyway I’ve been thinking about my mysterious dizzy spells and in doing so have been challenging Dr Google to come up with a more likely explanation than a potential heart murmur. Don’t misunderstand me, I’m happy to have my heart checked out but something about my symptoms being heart related just doesn’t add up.
And it’s this… my symptoms can be triggered by noise, such as notification alerts on my phone.
I am in no way an expert in medical matters but it seems unlikely that specific noises could trigger dizziness if that dizziness was because of a problem with the heart. And so I consulted the internet.
Search: loud noises cause dizziness
And I discover Tullio’s Phenomenon, a symptom defined as ‘dizziness induced by sound’.
So I read further and find that Tullio’s Phenomenon is a symptom of a number of ear conditions, one of which is Superior Canal Dehiscence (SCD).
SCD is a rare condition caused by a thinning (or hole) in the bone over the top of the semi-circular canal which leads to increased sensitivity to noise and pressure. Interestingly, it affects women more than men and is more common in the left ear.
SCD can be triggered by head trauma (can tick that box) and vertigo symptoms can be brought on by activity (running, tick) and loud noises (tick). Other symptoms include hypersensitivity to noise (big tick). Symptomatic SCD occurs in about 0.1% of the population.
Whether this is a plausible diagnosis or not would be up to my GP, but to me it makes more sense than anything we’ve come up with so far…
