You know it's a funny thing- only in the past month- and I am almost 7 months post CK that I feel light headed. I did get my eyes checked and I got new percription sunglasses! So that helps with driving, but now if I am at the computer, I get light headed for a moment, then it goes aways.
My tinnitus is about the same- dull humm during day, more high pitched at night, but nothing outrageous. If I have had a long day, I do feel more fatigued.
I am also on nasal medication which as the same side effects. My ear throbs if I don't take the medication, so I know it is somewhat sinus related but then I've got a tumor plugging the whole canal so it's not like my sinus can drain properly anyways. Also if I have a lot of sodium, my ear and lower jaw throb... like a whole bag of potato chips. I also get throbbing when I drive a lot, but I know that's me clenching my jaw rather than the tumor.
Long way of saying, yeah what you are experiencing is normal.
My latest remedy- lots of water and or ice tea - this seems to help- go figure!
Take care of yourself- Annie
