Micro Adenoma on my Pituitary.

First Post on this Site or any Site to seek help. But here goes. Basic Info. 61 year old female. 135lbs. 5'7" white
In 2008 I was diagnosed with a Micro Adenoma on my Pituitary. They wanted to remove it but I couldn't. Over the years I suffered with quite a few head injuries so I would always be told by Doctors about it being there. My headaches and dizziness were treated a few times but I reacted horribly to every medication they tried on me. Then they tell me I have Trigeminal neuralgia. One treatment went terribly wrong with side effects so I was never treated again. The Doctor also moved. This all occurred in VA. Five years ago I moved to CO. I began experiencing severe headaches again and dizziness. But the said I had moderate Altitude Sickness. But then when MRI's started being done again here comes the Pituitary Adenoma concern. But this time two neurologist gave completely different diagnoses. But I continued to suffer with Lightheadedness and dizzy spells .Now my Cardiologist's blame my heart Conditions. Electrical issues. Two months ago I had another MRI of the Brain. The Micro Adenoma on the Pituitary apparently is back. Because it supposedly disappeared two years ago. With all that said, I don't know who to believe. What I do know is that something feels wrong in my head constantly. It hurts to even touch my head sometimes. I have these bad headaches sometimes that are right in the center of my head behind my eye and nose. My cortisol levels have been very high now for two years. I have other blood results that no one can explain. My eye site is constantly changing. I believed until recently that I was going to have to live the rest of my life not knowing what was medically wrong with me. But then I found out about this forum. I feel hope. I am my Advocate.
