I have noticed the dent/ depression in the centre of my forehead is progressivly getting deeper, and more noticable. It appeared about a year ago and is now starting to worry me, it feels funny after I touch it, tingly and such, I ha e been getting headaches more frequently and when I am standing up recently i go really dizzy almost to the point of blacking out and my arms and leg can twitch violently so etimes as of I am havi g a fit..
