What Is a Subarachnoid Hemorrhage?
4. Symptoms
Forty-eight percent of those with SAH report a sudden, excruciating headache as their first symptom. The pain often extends into their eyes, resulting in an extreme aversion to light. The retinas may bleed, the optic nerves swell, and problems with vision can result.
Patients may become dizzy and nauseous. They may seem weak and unresponsive, lose consciousness, or have seizures. Other symptoms observed upon physical examination include elevated blood pressure, heart rate, and temperature. The heart may also beat irregularly.
