A Study Investigating Peripheral Cryoneurolysis in Adults With Chronic Migraine

The trial is a research study that tests a freezing technique called cryoneurolysis to see if it helps relieve pain in adults with chronic migraine. Chronic migraine is a condition that causes moderate to severe headache. In this study, the investigators want to evaluate the freezing technique in chronic migraine. The main goal is to see how much headache relief is experienced after receiving the treatment. The investigators will also record other important information about the participants. The study is looking to recruit 12 adults with chronic migraine to take part in the study. Participants will register their headache burden in a headache diary for at least 4 weeks before receiving treatment with the freezing technique. They will continue to register headache in the headache diary during the follow-up. After this initial treatment, participants with recurring headache can receive treatment as needed for up to two years. The results of this study will help us decide if the freezing technique may be viable treatment option for chronic migraine and enable us plan for further studies on this treatment.
