Same. The most frustrating part of my AN experience were the debilitating post-GK headaches. I distinctly remember my oncologist advising me to contact him immediately if I experienced any post-GK pain or discomfort. But, when I reached out to him after I began experiencing "ice-pick" headaches, constant dizziness and a sharp hearing decline, the response I got from him was, "Hmmm, I wonder what could be causing all that?" The frustrating thing was that I was not looking for a "cure" as much as simple reassurance that this was a common post-GK response (it is) and that the headaches and other symptoms would subside in a few months (they do).
The good news..., the headaches and other symptoms subsided in a few months!! 1 year after GK, I was symptom-free. 2 1/2 years later, I've never felt better in my life. My AN is something I rarely ever think about anymore. Annual MRIs show necrosis and slight shrinkage. Tinnitus is always there, but always on ignore.
So, hang in there, and never give up hope!! Try Aleve and ice packs for the headaches. Get rest when you can. Exercise and good diet will help when you start to feel better. A glass of wine now and then helps too
