Exploring the relationship between emotion and pain in rheumatoid arthritis, researchers report emotions may function as a stressor, promoting inflammation and causing pain symptoms.
Researchers believe the newly understood mechanism could yield insights into more precise future treatments for nerve pain and depression.
A new study reveals newborns who are stressed by their environment have a greater neural pain response following a routine skin lance than babies who are not stressed. However, the neural response is not matched by their physical reaction to pain.
A new rodent study uncovers a neural circuit in the brain that appears to govern pain-induced anhedonia. Altering the activity of this circuit restored motivation in pre-clinical models of pain.
On average, women who self-harm have a higher tolerance to pain than those who do not self-injure. Brain scans revealed greater connectivity between brain areas involved in pain perception and pain modulation in those who self-harm.
Researchers have identified biomarkers in the blood which can help determine the severity of a person's pain level. The findings could help doctors to accurately measure pain and stem the opioid crisis.
