    TLDR Adults with trichotillomania do not have different pain sensitivity to cold pressor pain compared to healthy individuals.
    The study investigated pain perception in individuals with trichotillomania (TTM) using the cold pressor test. It included 19 TTM participants and 14 healthy controls. Contrary to the hypothesis, TTM participants did not exhibit lower pain sensitivity or faster recovery times compared to controls. Pain tolerance and self-reported pain intensity were similar between the two groups. Additionally, no correlation was found between pain measures and TTM symptom severity. The findings suggested that adults with TTM do not experience analgesia to cold pressor pain, challenging previous assumptions about pain perception in TTM.
