I've been having headaches for a couple of months now, so I have convinced myself that I have a tumor or something. I finally went to the Dr. yesterday as I knew I would not feel better about this until I found some answers. The Dr. ordered a MRI for this morning. I have never had one done and didn't know what to expect, so I was quite anxious about it. Well, I lasted about 3 minutes in the MRI before I had a full-blown panic attack. My heart started racing beyond anything and I couldn't breathe. My body got tingly and numb feeling. I thought for sure I was going to die in there. I have always had anxiety, but I have never had a panic attack. It was the worst feeling in the world and I think I have PTSD from it. I called my Dr.'s office back and they have now scheduled me for a CT Scan and to take a Xanax before had. I have never taken Xanax before, so I am wondering if anyone out there knows if this will help with the anxiety? I've had CT Scans before, but my heart starts racing so bad from worrying and it so unpleasant. I am hoping the Xanax will help me stay calm and not have my heart race like that.
