If left untreated, shingles can lead to several complications that can significantly impact a person’s health and well-being. Some potential complications of shingles include:
Postherpetic neuralgia is a type of chronic pain that can last for months or even years after the rash has cleared
Vision loss or hearing problems if the rash affects the eyes or ears
Skin infections, particularly if the blisters become infected
Neurological problems, such as inflammation of the brain or spinal cord
