vertigo after cervical MBB?

has anyone seen a patient who develop vertigo after cervical MBB? i had a patient cervical MBB - C3-C6 bilateral - with no sedation. pt stated to me after first MBB that she had dizziness that lasted several hours but good pain relief response to MBB. I sort of didn't think much of her dizziness but it occurred again on the second MBB. now the legitimate concern is if this will occur more on a permanent basis after RFA. i've seen people treat cervicogenic vertigo with MBB/RFA but haven't... vertigo after cervical MBB?
