Social Security Disability Insurance (SSDI) can be a lifeline for individuals who are disabled by chronic pain. If approved, it can provide monthly insurance benefits to those whose disabilities are so severe that they cannot work a substantial amount. However, the application and approval process can be rigorous, and because assessing pain can be extremely challenging — given that it is invisible, subjective, and stigmatized — this may mean that some individuals with pain are incorrectly denied benefits.
