Inclusion Criteria: * Age between 20 and 70 years, both genders. * American Society of Anesthesiologists (ASA) physical status grades I or II. * Unilateral cervical radicular pain secondary to cervical disc prolapse affecting single nerve root which was refractory to conventional conservative and physiotherapy measures for 12 weeks or more. * All candidates received 1 millilitre of 2% lidocaine via an ultrasound-guided diagnostic nerve block and informed at least 50% momentary reduction of their pain. * Diagnosis was confirmed by cervical MRI and nerve conduction tests.
