Over time my right elbow has become very sore. Last night a light bulb went on inside of my head, and I realized why. I’m one of those people who creates a lot of condensation when I whistle and after each tune or two, I flick the moisture out of the fipple with a few pretty hard and quick downward waves of the whistle like someone would flick or wave a match to put it out. I practice for an hour or so almost every day and that adds up to a lot of flicking and a painful case of whistle elbow. I realize that this sounds very strange.
I think that I will blow the moisture out from now on.
