Hello Obsidian: Well... I can't say as I've had this particular experience. But I've certainly had a lot of experience with emotions causing physical symptoms. One of the ones I've experienced most, in times past, was shaking primarily from anxiety... but from anger as well. There were even a few times I can recall when I was so stressed out, I had difficulty talking. I suppose anger & anxiety affect each of us differently. I hope you are able to find a way to let go of the anger you are feeling.
