That's a good way to explain the feeling....it is kinda like my head is vibrating...I keep calling it an ADD type feeling because my head feels like it's jumbling all around and I can't get it straight. I just didn't know what to call it...
I've had mine out for almost 3 months and the symptoms come and go... when I first had it removed I was so scared because the symptoms were still there for so long but they seem to be getting some better now. I had the hot flashes and insomnia before and after removal too.
Good Luck...coming to this forum really helps...it gives you something to hold on to knowing that you are not alone..it has helped me alot!!
