Tingling pain in the lower left side of the neck may be caused by cervical spondylosis, muscle strain, trauma and other reasons. 1. Cervical spondylosis: prolonged bowing of the head or cervical intervertebral disc degeneration and other factors can lead to cervical spondylosis, which may lead to tingling pain in the lower left side of the neck. 2. Muscle strain: excessive muscle activity or maintaining a posture for a long time can lead to persistent muscle tension, which can cause muscle strain and tingling in the lower left side of the neck. 3. Trauma: When the lower left side of the neck is hit or squeezed by external injuries, it will cause damage to the soft tissues or blood vessels in the lower left side of the neck, which may cause stabbing pain. It is recommended to go to the hospital in time to clarify the cause of the tingling pain in the lower left side of the neck and carry out standardized treatment under the guidance of the doctor.
