Hi Cathie,
Sorry for responding late to your thread (I'm on this site less these days). Just wanted to say that I'm also about 4.5 months post-GK, and I also noticed my tinnitus was a bit louder, and my balance a bit more wobbly during the time period you mentioned. I live in Michigan which has also been slammed by the winter weather and extreme temperatures. Not sure if its because of the weather, or being 4.5 months out, but quite the coincidence that we both noticed a change around the same time! Just letting you know you're not the only one.
I don't know about you, but for me, part of the process has also been dealing with a hypersensitivity to every bodily sensation. Pre-AN diagnosis if I had a day where I just felt off, I'd chalk it up to getting a cold, not sleeping well, or just randomness, and move on. Now literally even the smallest change in physiological sensation is immediately noticed, monitored, and considered in a way that's not always helpful. Part of my "recovery" is to try to keep these changes in perspective.
Good luck and hope you're feeling better!
Adam
