Once in October and once in December I underwent surgery by Dr. Gary Steinberg at Stanford for a cavernous malformation first in the pons second midway up the brain stem. I have been dizzy for seven months can anyone speculate as to when it mght go away. And why is it there to begin with. Having dr. Stienberg is both a blessing in that he is one of the worlds best and a curse in that he and his staff are very busy I am concious of this and don't want to bother him/them with too many questions. However, I was in the hospital for roughly five weeks and He made a point to see me almost every day. I felt very taken care of.
