#5 -Severe Headache

If you are experiencing extreme headaches, it is probably a migraine. However, if it is not accompanied with other migraine-related symptoms, such as visual aura, extremely painful headaches could be a symptom of a brain aneurysm. These arterial clots are more common than one might think, and don’t make themselves known until the situation becomes serious. Smokers and people with a family history of aneurysms are more likely to get one than others. A brain aneurysm is extremely dangerous and emergency surgery is required to repair the damaged blood vessel.
