I had extreme fatigue for about 6 months, louder tinnitus for a while, and problems with being able to cope with stress. Work pressure was a bit much for me and had to scale back temporarily.
Nearly three years post Ck now and I'm doing BETTER than I have for at least 10 years, more energy and a much better outlook on things. Noise is still a bit of an issue, but nothing like it was for a while after treatment. AN is shrinking back to smaller than before CK and it's dieing. Nxt follow up in two weeks time, then we'll see! Tinnitus is the same, 5% lower hearing, no balance issues to speak of, except when tired or in the dark.
Happy with the decision, not a walk in the park for me, but now things are great.
By the way, I have a blog of my CK experience, if you send me a personal message I can forward it to you if you want.
Ciao, Lorenzo
