Hi, Bob....I can relate. I'm 3 mos. post-CK. Had an MRI three days ago. No change in tumor...but the good news: No residual negative effects from the radiation.
HOWEVER...the tinnitus in my head seems to be getting louder..and two nights ago...just sitting...a warm sensation in my affected ear...and for a moment it felt like my head was going to explode. It only lasted for a few seconds, but it seemed like an eternity. A little frightening. Of course, this happened AFTER I saw the Doctor and AFTER the MRI... Thought perhaps it was the dye they used for contrast. This was not the first time I've experienced this sensation...but it was, by far, the most severe.
As far as balance issues are concerned, when I asked the Doc about it, he said "the tumor is pressing on the balance nerve...that may not change for a long time." So I guess it's just "wait and see" if the CK treatment does it's thing, and actually reduces the tumor. I was told that all my symptoms would stay the same, for whatever length of time. NOT good news...but it's best to know the truth. Hoping you continue to "stay warm" in MN...it's been a really different "winter" for us in Florida...much colder than usual.
Have a good day....
Barbara
