I agree with Raster that it’s probably liver-related, especially if you’ve had intense treatment experiences lately. In the past when I’ve done detoxes/fasts/cleanses for different stuff, I’ve always had a period of time where I get extremely emotional. I have a friend who’s also a massage therapist who has an “angry” shoulder…she gets really irrationally angry when she gets bodywork done on it. A massage instructor I had in school told us about a friend of hers who became enraged when she practiced abdominal massage techniques on him when she was in school, even though he was excited for it and couldn’t explain himself after the fact. I think emotional memory can get locked into different areas of the body, and we only get rid of them through processing them properly, which I believe means experiencing them again.
