I have been searching for others with symptoms like this. I have a fluttering or vibrating sensation that occurs nightly, some more nights than others and varying in intensity. The frequency is always the same at around 6-8 Hz. It is preventing me from getting good sleep. I have tried muscle relaxers and anti anxiety meds and, aside from maybe making me sleep through the symptoms, nothing helps. It’s infuriating. I am in a stressful time of life so that might be it. I’ve been seen by a PCP and a neurologist and they have no clue what it is. Labs all normal. My chiropractor thinks it is deep neurological retracing but I’m doubting it. I really hope someone can provide more information on how to treat this. Would love to hear if some homeopathic method.
