2. Nausea and Vomiting
When the headache strikes, nausea and vomiting often follow quickly. This isn’t your average stomach bug – it stems from sudden pressure changes inside the skull. If it hits alongside head pain you’ve never felt before, your body could be reacting to internal bleeding or swelling.
3. Blurred or Double Vision
An aneurysm pressing on nerves near the eyes can distort your sight. You might suddenly see double images or notice everything going blurry. Vision changes like these are common when the aneurysm affects the optic pathways, and they rarely happen in isolation.
4. Stiff Neck
A painful, rigid neck – especially when you can’t touch your chin to your chest – often signals irritation around the brain’s protective membranes. This symptom frequently pairs with headache and sensitivity issues, creating a cluster of clues you shouldn’t ignore.
5. Sensitivity to Light (Photophobia)
Bright lights suddenly feel unbearable. This photophobia results from inflammation or bleeding irritating the brain’s lining. It’s a key neurological sign that separates a simple headache from something far more serious.
6. Seizures
A first-time seizure in an adult with no epilepsy history is alarming. It can occur when an aneurysm disrupts normal brain electrical activity. Research shows seizures appear in up to 20% of rupture cases, making this one symptom that always warrants an emergency evaluation.
7. Drooping Eyelid or Facial Weakness
One eyelid may suddenly droop, or part of your face might feel numb or weak. This happens when the aneurysm compresses nearby cranial nerves. It can look like a mini-stroke, which is exactly why you need to act fast.
