Hi Noelle,
The balance symptoms you've described sound fairly classic for someone who has one vestibular nerve being compromised. If your AN is pressing on the vestibular nerve, the brain may be recieving odd vestibular input from the AN side. This is probably extra confusing if the input is good one day and affected the next. It usually takes some time for your brain to compensate and relearn balance after AN treatment, if the vestibular nerve is affected. If your vestibualr nerve is slowly compromised before treament, balance may have already compensated to some extent. These AN patients may have better balance imediately post treatment than patients who lose a vestibular nerve with AN treament and lose vestibular input from the AN side suddenly. Even patients who lose the AN nerve suddenly, relearn balance fairly quickly. The first few days are a little rough, but the brain relearns quickly.
Many patients find that doing Vestibular Retraining therapy, with a therapist who specializes in this type of therapy, after treatment helps the balance system relearn and compensate more quickly. Your AN treament team probably works with a therapist and can refer you to the right person.
Regards,
Rob
