My husband has shingles around the left side of his face. His eye is swollen shut and he has extreme pain in his eye. We have gone to the emergency room twice with him and they see no shingles in the eye. We went to the U of M which is a good hospital. So my question is how do we know if shingles have actually entered the eye? He has already suffered all of the symptoms but has no shingles in the eye. We don’t want to keep going to the emergency room.
