Wow, this is great to come across this thread and hear people's experiences, because I just went swimming today for the first time in a very long time (since before my accident 2+ years ago). It felt great and can't wait to go back later in the week. My time in the pool was only 10 min of simple laps, partly with a kick board. It didn't occur to me that this might help my ongoing symptoms, but everyone here seems to have at least had a positive thing with swimming, great!! :-)
