Summary

This study will follow 80 people with chronic pain (like back, hip, or nerve pain) who are getting a procedure called cryoneurolysis, which uses cold to temporarily block pain signals. Researchers want to see if it leads to meaningful pain relief and better daily function over 12 months. Participants will fill out questionnaires about their pain and disability before and after the procedure.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
cryoneurolysis (a procedure that uses extreme cold to temporarily block pain signals from nerves)
What this could lead to
If successful, this could show that cryoneurolysis provides meaningful, lasting pain relief for people with various chronic pain conditions.
What could go wrong
This is a small, early-stage study with no comparison group, so results may not apply to everyone. The procedure is not a cure and pain may return.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Diagnosis of chronic pain (generally pain duration of at least 3-6 months) localized to an anatomical region appropriate for cryoneurolysis as determined by the treating physician. * Planned cryoneurolysis procedure as part of standard clinical care. * Ability to provide written informed consent. * Ability and willingness to complete baseline and follow-up questionnaires. Exclusion Criteria: * Cryoneurolysis performed as part of a separate investigational trial in which data sharing is not permitted. * Active infection or other clinical contraindication to the procedure as determined by the treating clinician. * Life expectancy of less than 12 months in the judgment of the treating clinician. * Any condition that, in the investigator's opinion, would interfere with study participation or completion of follow-up, such as severe psychiatric instability or active substance use that precludes reliable follow-up
