Always be concerned when dealing with an aneurysm! I waited too long. It got bigger and burst unexpectedly. If everyone hadn't of done things so effecient i might not be here today. I also experienced severe headaches, loss of sight, dizziness, among other things. Doctor Chris Taylor performed an angiogram to embolize the bleed. Ever since then i have known 6 different people that weren't as lucky as i am. GO see a Doctor!!
