This study tests a treatment called Transcatheter Arterial Micro-Embolization (TAME) with a special agent, Nexsphere-F, to help people with long-lasting pain in their elbows or wrists. The study looks at how well the treatment works and if it is safe. People who try this treatment are those who have tried other pain relief methods without success. The study lasts 6 months, with check-ups at 1 month, 3 months, and 6 months to see if the treatment helps reduce pain and improve movement. During these visits, doctors will check pain levels using a tool called VAS (Visual Analog Scale) and other tests like QuickDASH and PRTEE to see how well you can use your elbow or wrist.

• The study is open to people aged 19 to 80.
• Participants must have tried other treatments for at least 3 months.
• Doctors will check for any unusual problems during the study.
