Shaking Things Out

Had a good practice this morning--steady and grounding. I've been experiencing a tremor in my right arm--like an involuntary shaking. As I was doing Wu Ji my arm started twitching and shaking. I just let it be and let the shaking happen on its own without trying to influence or stop it. The arm shook steadily for quite some time and then quietened and seemed to fill with Qi.

I don't where the thought came from to just let the arm do its thing--to fully let go of the tensions in the arm and allow the shaking, and finally, the quietening to happen. My right arm seems to feel more sensitized from the experience.
