Hutchinson sign results from having shingles on the face.
The biggest concern is if the shingles flares up in the eye. THIS IS SERIOUS.
Because of the trajectory of the facial nerves, the same nerves that go to the eye also go to the tip of the nose.
Thus, if a shingles lesion appears at the tip of the nose, the eye is in danger of being affected.
Best thing to do is consult an ophthalmologist.
