I seem to be having these lately. I wake up late at night and ache all over, but it is emotional. I also feel very bad emotionally when it is happening. In the morning it is gone. My abuse involved repeated rapes late at night by a teacher at a boarding school, so it makes sense. I think I may have had this sensation all my life, since the trauma, but only now am able to recognize it consciously. It is horrible, but I use controlled breathing to get through it. If anyone else out there has "body memories" and would like to talk about it, please let me know.
