Cannon sets off vertigo at Civil War re-enactment
Woman had 'sudden onset of dizziness' and headache with the blast, GP writes
A woman watching a Civil War re-enactment experienced vertigo for four days after being affected by the blast of a cannon firing metres away, a GP reports.
Indirect trauma from the cannon blast triggered the 37-year-old’s benign paroxysmal positional vertigo (BPPV), says Ohio GP Dr Ryan Dale Kauffman.
Almost a quarter of BPPV cases are the result of traumatic causes, but this appears to be the first case of vertigo resulting from non-contact forces reported in the literature, he says.
