I had Cyberknife 21 months ago.
Before treatment I had moderate hearing loss, mild tinnitus, that plugged ear feeling, wonky head, was lacking energy, and for a while had problems typing, and words somehow came out wrong while speaking. Balance also was not great.
Straight after Cyberknife all my symptoms got worse. Then slowly things got better.
Now, my hearing is back within the normal range, tinnitus is gone, balance is good again.
I feel very fortunate indeed to have my hearing improve back to normal levels, and all of the other annoying symptoms disappear.
I still get the odd day where things don't feel quite right, like very mild tinnitus and my balance being a bit off, but I feel that I am still improving after 21 months. I am pretty close to a full recovery, with no symptoms on a majority of days, and I really didn't think that was possible when I started this journey.
I know that hearing can take a turn for the worst with radiation even after 21 months.. fingers crossed it remains good.
