noun
analgesia
an-ul-JEE-zhuh/ˌænəlˈdʒiːʒə/
Absence or relief of pain without loss of consciousness.
The clinician assesses the patient's analgesia while he remains awake.

Etymology
“Without” and “to feel pain” identify the particular sensation that is absent. Although the Greek noun could mean insensibility more broadly, the medical meaning concerns loss of pain sensation while touch remains perceptible.
In context
the one who took epidural had excellent analgesia. Whenever I asked her, "Do you have pain?" Her pain scores were less near zero only.
More examples
