I want to know if I may have a brain anyuerism. I couldn't afford to get the MRI I was supposed to, and now my symptoms are getting worse. Help!

Which symptoms? Why is there an idea that an aneurysm is even present? Were you told that bad headaches occurring sporadically were due to aneurysm, because that is not a real relationship. Many aneurysms are congenital berry, and unless quite large, do not rupture. Why should you pay a month's wages for an MRI unless your exam is abnormal and points to structural mass? Get a second opinion.
