One of the most significant complications of shingles occurs when the rash appears on the face, close to the eyes. This can damage the cornea, causing vision loss, and requires aggressive antiviral treatment. In some instances, neurological complications such as facial paralysis, brain swelling, and hearing or balance issues can develop. It is also possible for a mild to severe infection to occur at the site of the blisters, which will require antibiotic pills and topical ointment.
