First off, I never had any issues while diving unknowingly with an AN, which I'm told I had for several years. When I was diagnosed with an AN, it was 3cm at the time. I was diving a few days prior to that diagnosis. I went on a trip shortly after and did some free diving without any problems. I guess the question I have for you is what concerns do you have about diving with an AN while on a watch and wait status. If your primary concern is about balance issues then I could see your worry. In that case, I feel it would entirely depend on the individual and whether or not they are having balance issues from the AN. As a diver, you are aware of vertigo issues while diving in cold water, diving with a cold, etc. I'm assuming you would take the same precautions then while diving with an AN. Balance issues and diving don't make for a safe dive, so that would be the limiting factor for anyone diving, in my opinion.
I dove for the first time 4.5 months after my trans lab surgery and had no issues. So there is life after AN removal. I was free diving that weekend to depths of 25 feet and didn't have any vertigo issues, no problems equalizing or pressure build up. I felt great the entire weekend. I wouldn't let the AN diagnosis hold you back from anything as long as you aren't having symptoms that would
preclude you from being safe.
If your aren't having symptoms, enjoy life to its fullest! If you are having symptoms, be safe and enjoy life to its fullest.
