I have had mine out since Sept. 17th. My vibration in my head started in the beginning of august and I had a MRI which came out normal. Since I had it removed the vibration has moved around my body, mostly still in my head but sometimes in my body.It really worries me because it has never went away like my other symptoms. My other symptoms come back around my period but are weaker every time. Now I am having a problem with heartburn everyday so bad that the other day I got sick in the middle of the night and had a pain up high in between my ribs also a heaviness in my chest so I am going to my Dr. this morning. I am wondering if I have a ulser from stressing over what has happened to me from this evil thing!! I am going to talk with my Dr. today and tell her I am still having the vibration in my head an body see what she says. I will let you know, and please let us know if you find out what it could be caused from.Take care
