Could Nausea And Dizziness Mean Recurred Spinal Leak?

Hi, may I answer your health queries right now ? Please type your query here... My wife had a 3 level fusion 8 weeks ago and her spinal sack was cut which required the doctors to go in a second time 4 days later to repair. Today she is complaining of nausea and dizziness just like when she was in the hospital with the spinal leak. Could it be leaking again after 8 weeks?
