Scalp Shingles Illustrated: Symptoms, Imagery, and Additional Information
Shingles, a painful rash that follows the path of a nerve on one side of the body, is a common health concern, particularly among individuals aged 50 years and older. This condition, also known as herpes zoster, is caused by the reactivation of the varicella-zoster virus - the same virus that causes chickenpox.
The onset of shingles typically begins with pain, burning, or tingling sensations in a specific area on one side of the body. This is followed by the appearance of a rash, which starts as small red or pink spots that develop into clusters of fluid-filled blisters. In darker skin tones, these blisters may be less visibly red, instead presenting as raised, bumpy, and discolored areas.
The rash usually appears in a stripe pattern along a nerve distribution, mostly on one side of the torso, but can also appear on the face or other parts of the body. As the rash progresses, the blisters eventually break open, crust over, and heal over 7 to 10 days.
Common symptoms associated with shingles include pain or burning sensation in a localized area before the rash appears, clusters of fluid-filled blisters forming on a red base, itching or numbness in the affected area, flu-like symptoms such as fever, headache, and fatigue, sensitivity or extreme tenderness of the skin in the rash area, and possible complications like postherpetic neuralgia (chronic nerve pain after rash resolution), eye involvement (which requires urgent medical attention), and secondary infections from scratching.
Diagnosis of shingles is usually based on visual assessment and accompanying pain, with doctors also conducting laboratory testing to confirm the diagnosis.
While there is no cure for shingles, early treatment with antiviral medications like valacyclovir, famciclovir, and acyclovir can speed up healing and relieve severe pain. Alternative approaches to treating shingles include applying a cool washcloth, calamine lotion, using a mild, fragrance-free shampoo, avoiding scratching the scalp, taking a bath with lukewarm water, getting plenty of rest, eating a nutritious diet, and avoiding stress.
The Shingrix vaccine, recommended by the Centers for Disease Control and Prevention (CDC), is approximately 90% effective in preventing shingles and postherpetic neuralgia (PHN). It is recommended for people ages 50 years or older and those over 19 years old with weakened immunity.
It is important to keep the rash covered with loose clothing or a non-sticky dressing to prevent spread. People should also be aware that shingles is not transmissible to another person, but a person could contract the virus and develop chickenpox if they have not had it or the vaccination.
