Inclusion Criteria:  Pain in upper quadrant associated with cervical spine eliciting unilateral neck pain. Paresthesia and numbness in the neck and arm for at least three continuous months Active movements of cervical spine (extension, lateral flexion to either side or ipsilateral rotations) and arm movements reproducing pain. Symptom reproduction on passive movements in the same pattern as with active movements. Elicitation of adverse response (in terms of range of movement and reproduction of symptoms) to neural tissue provocation testing of median, ulnar and radial nerves and subsequent symptom alteration with neural tissue differentiating maneuvers. Tenderness at transverse processes of cervical spine (nerve roots), nerve trunks of median, ulnar and radial nerves at different anatomical locations in the course of respective neural tissue. Hyperalgesic related cutaneous tissues on palpation (tender points). Evidence of a related pathology (example: radiological evidence of cervical disc pathology in the vicinity of involved nerve roots or evidence of stenosis at cervical neural foramen as diagnosed by a qualified musculoskeletal Radiologist) provoked or spontaneous paresthesia and pain with radicular distribution Positive results in the following tests: Spurling, Distraction, and Upper Limb tension test. Diagnosis will be based upon subjective presentation of patient's pain pattern which includes somatic referred pain and neurogenic radiating symptoms.  Exclusion Criteria:  Bilateral symptoms (due to unilateral nature of lateral glide mobilization technique). History of spinal surgery Systemic diseases besides neck pain. Vertebral infections. Presented red flags. Used analgesics within 48 hours before initial assessment.
