Those who had received saline or lidocaine will receive ultrasound guided cryoablation. Individuals, who had previously been given ultrasound guided cryoablation without any improvement, may opt for another denervation procedure at 4 weeks. All of the participants will be followed up at 3 months post procedure to determine the magnitude and duration of pain relief.\n\nStudy procedures will be conducted by the principle investigator who is a Board Certified pain management attending physician and an expert in performing ultrasonography guided interventions The cryoablation device is routinely used to treat various painful pathologies at Mount Sinai and Beth Israel pain management offices.
