Hi, I experienced a dizzy spell during the night when I moved my head in bed, again when I got out of bed this morning and a couple during the day when I bent over and stood up quite quickly (which I then avoided). I have just laid down on the bed and experienced a dizzy spell, room spinning and thought I was going to pass out! The back of my head/neck does not feel quite normal and yesterday I tripped when going out of the back door, not sure if I jarred something which may have caused the dizzy spells. Thanks
