Melzack and Torgerson developed the McGill Pain Questionnaire which rates pain quantitatively by sensory, evaluative, and affective descriptors.
VAS is the most common pain scale for quantification of endometriosis-related pain and skin graft donor site-related pain. [5] A review came to the conclusion that VAS and numerical rating scale (NRS) were the best adapted pain scales for pain measurement in endometriosis.

Acute or chronic pain can be directly measured by pain scales such as the numerical rating scale (NRS) and visual analog scale (VAS). [ 15 ] [ 16 ] [ 17 ] A serial pain scale from 0 (no pain) to 10 (worst pain imaginable) can quantify pain intensity.
