These things are straight-up terrifying.
The Absolute Worst Headaches Of Your Life
This pain occurs because most aneurysms are in the subarachnoid, or a small, enclosed space just outside the brain, and when they burst, they flood that space with blood, says Putrino. The quick change in pressure is what you feel as a skull-splitting headache coming out of nowhere. “The subarachnoid space has lots of nerve endings, so people start to experience very intense pain,” he says. This headache can be constant or ebb and flow, he says, as each rupture is different. Some may slowly leak while other are torn open all at once.
Nausea and Vomiting
Of course, you can experience nausea and vomiting for a whole host of reasons, but if they occur with any of the other brain aneurysm symptoms on this list, you should go to the emergency room, he says.

A Ridiculously Stiff Neck
And, yes, this will feel way more intense than “I slept wrong last night.” So if you experience severe neck pain, play it safe and call 911.
Facial Tingling and Drooping Features
While it’s true that some stroke and brain aneurysm symptoms are similar, both conditions warrant immediate medical treatment, so get to the emergency room ASAP.

Blurry or Double Vision
“If you notice these vision symptoms come on after you get a bad headache, and then maybe you get nausea, that means something is going on neurologically,” he says. Be on the lookout for escalating and combined symptoms.
Obviously, if you or anyone else experiences a seizure (and it’s not typical, like with epilepsy) immediately call 911.
