Hi, Buzzy - and welcome. I always regret seeing another person having to deal with an acoustic neuroma, cystic or otherwise, but I'm pleased that you've found our website and decided to check out the forums, register and post a question. We'll try to help. You've received some good information already and the only thing I can add is encouragement in the form of relating my AN experience.
I was 63 and diagnosed with a 4.5 cm AN in 2006. I underwent a partial resection of the tumor, cutting off it's blood supply and reducing it's overall siaze, making it amenable to irradiation. Three months later, I underwent a series of 26 FSR treatments intended to - as my doctor explained it - destroy the remaining tumor's DNA. Subsequent MRI scans have shown that the remaining tumor shows both necrosis (cell death) and some slight shrinkage. Both doctor and patient are elated. My recovery was relatively rapid. I resumed driving barely two weeks after having the surgery. I've pretty much resumed my normal, active life. Although I'm retired, I'm hardly sedentary. Many AN post-op patients run half marathons and engage in other fairly strenuous physical activities within a few weeks or months of AN surgery. However, one size does NOT 'fit all'. Some AN post-op patients struggle with a variety of issues, but many do not or whatever they have to deal with resolves in time and with effort to rehab on their part. It isn't all gloom-and-doom. However, with acoustic neuroma surgery - and radiation, for that matter - there are no guarantees, as any doctor will attest.
I join others in suggesting you consult with a doctor (or 2) that perform(s) both surgery and radiation to help avoid receiving biased opinions, which are rampant when it comes to AN treatment. Meanwhile, I wish you the best and trust you'll be a frequent contributor on the forums as we offer information and of course, our full support, no matter what your choice of treatment to address your AN.
