• Numbness
• Neck pain

How to know you have subarachnoid hemorrhage?

• Medical history, physical examination and neurological examation
• Head noncontrast CT: Head CT may show evidence of aneurism and hemorrhage area. In some cases, CT scan may be normal.
• Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA): These images are occasionally used to diagnose a subarachnoid hemorrhage or find other associated conditions.
• Cerebral angiography: This test can show small aneurysms or other vascular problems. It can locate the exact point of the bleed and can tell whether there is blood vessel spasm or not.
• Lumbar puncture: When your severe headache is suspected subarachnoid hemorrhage but head CT shows normal, the doctor may order this test. During this procedure, the patient lies on the side, with knees pulled up toward the chest, and chin tucked downward. After injecting the anesthetic into the lower spine, the doctor insert a spinal needle into the lower back area to measure CSF pressure and collect a sample. Patients with subarachnoid hemorrhage will have blood in the spinal fluid.

When to seek urgent medical care?
