I was troubled with balance and other issues for 7 full months after surgery. Walking with head movements helped, but I did not overdo it. I did exercises morning, afternoon and night with rest after each session. We cannot force ourselves to recover, or to recover faster, than our brains and cranial nerves are able to. Feeling frustrated and impatient just adds stress to an already difficult process. Recovery isn't a race, it is recognizing small improvements and seeing progress. The rate of recovery varies for each person.
I am now just over a year and feel fine, though I still have moments of difficulty and experience wonkiness at times, but it is very minimal compared to what it was a year, and even 6 months,
ago. Cranial nerve recovery can take up to 18 months according to both my surgeon and ENT. I am sure you will improve with time, most of us do. Good luck
