纖維肌痛； 1980年開始出現症狀，表現為全身疼痛，並因疼痛而難以入睡，尤其是在體力消耗後。 次聲的 8 [New Design:  CHI Palm] was placed under the bed for continuous use during the night (Balance). Experimented with positioning the I8 under middle of back and sacrum. Pain and Sominex tablets have now been eliminated. Several times, I have forgotten to turn the machine on. Wondering why I had not slept as well, I discovered I had not turned it on. So far, middle of back position seems to be more effective. Reduced pain, better quality of sleep and perhaps more energy.
