Shingles is caused by the varicella-zoster virus (VZV), the same virus that causes chickenpox. After a bout of chickenpox, the virus lies dormant in the body and can reactivate when the immune system is weakened, leading to shingles. This isn't just a skin condition; it can affect other parts of the body, including nerves, the heart, eyes, and brain. Older adults are more susceptible and at greater risk of serious complications. Early detection and recognizing the initial symptoms are crucial for effective treatment.
Nerve pain is often the first sign of shingles. Some describe the pain as similar to labor pains, post-surgical pain, or an electric shock.
Burning blisters are a common symptom. Shingles typically manifests as fluid-filled blisters that eventually burst and scab over. These blisters can appear on one side of the body, such as the face, abdomen, chest, or back, and last for 2-4 weeks. Sometimes, these signs can be mistaken for insect bites or eczema, leading to delayed diagnosis and treatment. In some cases, the pain may precede the rash.
A red rash can develop within a few days of the virus reactivating. This rash usually appears on one side of the body or face. It can be red, deep pink, purple, or brown, depending on skin tone. The rash is often itchy and accompanied by a burning sensation.
Flu-like symptoms such as mild fever, headache, fatigue, and muscle weakness can also occur. Fever is the body's response to infection and inflammation and can accompany more serious illnesses like shingles.
Itching and sensitivity to touch are common in the affected areas, along with pain. Scratching should be avoided as it can increase the risk of infection. The skin can become so sensitive that even light touch causes pain or discomfort.
In some cases, shingles can have lasting complications. Postherpetic neuralgia, a type of nerve pain, can persist for months or even years after the rash has cleared. This condition is more common in people 50 years of age and older. The pain can also lead to loss of appetite, difficulty sleeping, weight loss, and fatigue. Vaccination is a preventative measure against shingles.
