Do a search for tremors and ratcheting, here on the forum. You will find that a LOT of us have this! Some neuro's have diagnosed folks with benign essential tremor, but in my case, it has been self-limiting and it waxes, and wanes now. I only tremor every once in a while, and it will last only a few days at a time. In the beginning, it was constant, and I felt ratcheting in nearly every muscle, as well; including neck, my trunk, my legs, my shoulders, and even my diaphragm. I would actually feel a strange hesitation in my chest when I would breathe. My husband has heard it, himself, and commented on it. Very bizarre, but all "normal" for bfs. Blessings, Sue
