Hi I'm 68 and very very frightened. For three days now I've been getting what feels like my head/brain "jumping" when I move my head a certain way. At the same time I get a sort of "ching-ching" noise in my head, my vision "jumps" and I get vibrations like a very mild painless electrical charge down the side of my tongue, down my arms and across the soles of my feet. I can bring the "brain jumps" on as well by turning my eyes hard into the corners as far as possible. I go a bit lightheaded whilst the "jumping" is going on. and it lasts for about a second. Then I'm ok til I move my head a certain way. I've no pain or numbness but have osteoarthritis of the neck and spine. Can anyone help me with this? I'm sitting here on a Saturday with all the doctors sugeries closed feeling sooooo frightened. Thank you, Sarah.
