Hello I am new here and just got a call from my dr that he is unsure but thinks I may have a small anneurism in the front of my head! And that I need a further test to be sure! I am way confused how can you not tell if it is or it isn't? It was actually the nurse who called me and she said it could be a dirty spot on the machine or something but don't worry!!!! Wth? Please help with any info!!!!
