Welcome to ANA, I'm sorry you're struggling. My AN was small, but I was suffering with severe vertigo attacks. I chose surgery at the age of 54. I also suffer from tinnitus and it has gotten worse after surgery, but I am trying to find ways to control it. I'm on a diuretic, I stay away from Nitrites, Sulphides MSG etc. I stay away from caffeine and alcohol. I try to get quality sleep. All of this has helped, not everyday, I still have bad days and better days. My brother in law is a retired fireman. Many of them have severe tinnitus due to their exposure to sirens. He was given a prescription that he claims really helps him. I am going to find out what it is, see if my doctor will prescribe it, and I will post my results here.
In reference to growth, I think the best person to ask is your doctor. What I have been told is these tumors do not grow linear. Meaning, they don't just grow a certain amount each year, but can grow in spurts or even stay dormant. Again this is not an official medical piece of information, but it is something you will need to check with your doctors. As far as choosing surgery or CK, or watch and wait, my advice is learn as much as you can and make the very best decision that works for you. Stay connect to this site, it's filled with great people who understand, and who have a wealth of knowledge as well as first hand experiences.
