Shingles is a viral infection that causes severe nerve pain and can potentially lead to blindness when it affects the face.
Shingles results from the reactivation of the varicella-zoster virus, which causes chickenpox. After recovering from chickenpox, the virus remains dormant in the body for years. When the immune system is compromised, the virus can reactivate, leading to shingles. Older adults and people with weakened immune systems are particularly at risk. The appearance of shingles is a clear sign that the immune system has started to weaken and requires immediate attention.
Early Signs
Early signs of shingles may include the following:- Localized pain and sensitivity: This typically occurs on one side of the body, following the path of the nerves. It is commonly felt under the arms, on the side of the chest, or on the back.
- Skin itching or burning sensation: This sensation usually begins a few days before the rash appears and becomes increasingly noticeable.
- General fatigue: Some people may experience feelings of weakness and tiredness, sometimes accompanied by mild fever and headaches.
- Localized redness and swelling: The skin in the affected area may appear red and swollen.
Potential Complications
Shingles can lead to various complications depending on the area of the body affected:- Postherpetic neuralgia: The pain may persist for several months or even years after the rash has resolved.
- Skin infections: If the affected skin area is not properly managed, secondary bacterial infections may develop.
- Eye damage: Shingles can sometimes appear around the eyes, potentially impacting the eye itself and damaging the cornea, which may result in vision impairment or even blindness.
- Hearing loss: If shingles occurs near the ear, it can affect hearing and lead to hearing loss.
- Nerve damage: This condition may affect motor nerves, causing muscle weakness or even paralysis.
