Herniated discs between C1 and C4 levels cause an irritation of nerves in the region and may lead to various symptoms commonly a tingling sensation
of the face and head supplied by the Trigeminal nerve
or the fifth cranial nerve
. Any damage to the facial or the seventh cranial nerve can lead to a palsy of the facial muscles
supplied by that nerve. Is there any asymmetry between the sides of your face? Is there a drooping of the angle of your mouth or some weakness in shutting the affected eye? The watering may be a result of weakness of the orbicularis oculi which refers to the muscle that helps the eye to close forcefully. Certain fibres called parasympathetic nerve fibres upon stimulation cause reflex tearing. This is not common but a possibility. Treatment is directed towards the herniated discs as the problem does not arise from the eye. Continue treatment as directed by your orthopedic surgeon and your ocular complaint should reduce with time.
