Hi. My name is Alexis, and I m 16 years old. In September of 2011 I was diagnosed with a Rathke s Cleft Cyst on the stem of my brain. I have been to many doctors and they all had me doing no physical activity, because I might hemorrage my cyst. But I recently changed doctors again, and this time I did hemorrage it, he doesn t really know much about this, and I was just wondering how dangerous it was, and what it could do to me?
