Pain asymbolia

From Wikipedia, the free encyclopedia

Pain asymbolia is a condition in which pain is perceived, but does not cause suffering. This usually results from injury to the brain. Preexisting lesions of the insula may abolish the adversive quality of painful stimuli while preserving the location and intensity aspects.
