Shingles refers to a viral infection caused by the varicella-zoster virus (the same virus that causes the chicken pox). According to the Mayo Clinic, symptoms of shingles include a painful, red and burning rash usually located on one side of your body. This rash can develop into fluid-filled blisters. If you suffer from shingles, you should be aware of its complications.
Postherpetic Neuralgia
If shingles is left untreated, you may develop postherpetic neuralgia. According to the Mayo Clinic, this is a condition where the excruciating pain resulting from shingles persists despite the disappearance of your blisters. Your nerves (special fibers in your body that allow cell-to-cell communication) are destroyed and the pain signals reaching your brain become disorganized, so your sensation of pain is constantly provoked.
Ramsay Hunt Syndrome
Ramsay hunt syndrome, also called herpes zoster oticus, is another complication of shingles. According to the National Institute of Neurological Disorders and Stroke, the varicella-zoster virus infection spreads to the nerves in your face. When this occurs, you may experience severe ear pain, facial paralysis and a rash around your face, mouth, ear, neck and scalp. Dry mouth, hearing loss and tinnitis (perception of sound in your ears) are other common symptoms of ramsay hunt syndrome.
Herpes Zoster Opthalmicus
According to the Family Doctor website of the American Academy of Family Physicians (AAFP), herpes zoster opthalmicus (HZO) is another complication of shingles. Symptoms include a rash with blisters around your forehead and eyes. Pain and swelling of your eyelids are additional symptoms of HZO. The Mayo Clinic states that this eye infection can ultimately lead to blindness if left untreated.
Skin Infection
The Mayo Clinic states that if your shingle blisters are not promptly treated, the bacteria can infect the blisters and cause a skin infection.
