Continued balance issues after labrynthectomy and cochlear implant

[reesekathy48]

I had a labrynthectomy and cochlear implant done almost a year ago and was in physical therapy until about 2 months ago. I am still experiencing balance issues (especially after I have been sitting or getting out of a car). I feel some sort of mental exhaustion at all times. Sometimes its hard to think straight I feel very foggy in the head. Is this normal?? How long does it take to feel normal again? Or should I be concerned?
