I have one wide neck aneurysm in the left side of my brain1 1/2 centimeters (2005) the Dr. did a coil embelization and two mesh stents. I've gone every year since for MRA's. This time we found another aneurysm around the same area but ist much smaller. only 2mm. I have been having dull headaches localized on the left side for about 3 weeks. Could this be caused by the aneurysm?
