This might occur when you turn your head up or down, when you lie down, or when you turn over or sit up in bed The signs and symptoms of BPPV can come and go, with symptoms commonly lasting less than one minute. Episodes of benign paroxysmal positional vertigo can disappear for some time and then recur. Treatment: Positional manouvres such as Epley’s manouvre, Gufoni’s manouvre etc are the treatment of choice. Repeated manouvres are occasionally required. Supportive treatment with antivertigo drugs is sometimes needed.
