How do you measure how much a headache hurts?

The severity of headaches is typically measured subjectively using a pain scale:

Verbal Rating Scale (VRS):

- No pain

- Mild pain

- Moderate pain

- Severe pain

- Excruciating pain

Numerical Rating Scale (NRS):

- 0 - No pain

- 1 - Minimal pain

- 2 - Mild pain

- 3 - Moderate pain

- 4 - Moderately severe pain

- 5 - Severe pain

- 6 - Very severe pain

- 7 - Extremely severe pain

- 8 - Intolerable pain

- 9 - Worst pain imaginable

- 10 - The most excruciating pain possible

Visual Analog Scale (VAS):

- A 10-centimeter line, anchored with 'no pain' on one end and 'worst imaginable pain' on the other end.

These methods allow individuals to rate the intensity of their pain based on personal perception and experience during a headache episode. Some healthcare providers may also consider additional factors like headache frequency, duration, associated symptoms, and impact on the person's daily activities, to get a more comprehensive understanding of its severity.
