By Mayo Clinic staffMost of the time, people who undergo the procedure do experience relief, but there is a high recurrence rate and it's not unusual for the condition to return within the first year after successful treatment. If the condition does return, then a repeat of the canalith repositioning procedure can be used. However, it may be necessary to repeat the procedure several times to relieve your symptoms. Talk to your doctor if your symptoms don't improve.
