Dear Cindy, I have a pituitary tumor and have had my share of anxiety/panic attacks. I believe you said the tumor is gone ? according to the latest MRI? I hear that some tumors can become so small they do not show up on the MRI but are there and causing problems. I have come to believe my tumor is causing me to have low blood pressure when I am sitting or standing for a short while. Like driving or in a grocery line. I believe this low blood pressure makes me dizzy and brings on anxiety/panic attacks from being scared of the dizziness -- either consciously or subconsciously. I could be wrong but it fits too well for a reason for it. I have more info on the low bp and anxiety if you would like it. I hope and pray your daughter gets better. She is too young to have to go thru all this. Pam |
