I have not had surgery for my AN as it has stayed small. My balance and dizziness are also a result of the subtotal temporal bone resection I had in 2012 on the opposite side for the squamous cell carcinoma growing there. Weather and sinus pressure definitely affect my symptoms. The most amazing part of this recovery has been seeing the way that the brain heals and retrains itself to accommodate for the changes and deficiencies that are the result of surgery. Mayo nurses and doctors told me to be patient, and continue to challenge myself to allow the brain to retrain to what is needed. Just simple things like walking on an uneven surface, and moving my head side to side while walking have been exercises to help to make improvements. And vision is a major part of balance, so darkness or any loss of vision is also a challenge. As a veterinarian I know that nerve tissue is the slowest tissue to heal, and here I am 6 years later, still seeing changes and improvements in my condition. It will likely never be normal, but the new normal is tolerable with some adaptations. As for surgery recovery time, it seems to get longer the older I get. At the age of 62, it took a full year to feel "normal" again after my last thoracotomy. My stamina has never returned to what it was. So give yourself time, continue to challenge your brain by doing the things that you have difficulty doing, and expect that there is still time for improvement. Try not to get discouraged. You are still alive.
