If you think you have an aneurysm, you really should get to an emergency department. No one can diagnose you with this - or rule it out - online, so getting checked by a medical professional promptly is your best best.
Most aneurysms don't cause any problems. Obviously, they can rupture in rare cases, and that's very serious. You don't present with typical symptoms of one, but something IS happening, even if it's not an aneurysm, and it's worth getting checked out by at least your family doctor to find out what it is.
