I’m so glad that I found this group. My vibrations feel strong & electrical and frightening when they are in my head. I also have just a very steady vibration in my abdomen and chest. But my symptoms are very sporadic- maybe feeling them for a few nights in a row - then nothing for the next month. Once, after experiencing head vibrations, I had a brief period of blurry vision. I was told by a neurologist that it could be small mini-strokes or perhaps late onset (I was in my mid 50’s then) multiple sclerosis. I haven’t been to a neurologist in the last 10 yrs. I have heart stints and moderate carotid artery blockage. I wonder is it’s all connected.
