Disease 8. Shingles: A Painful Viral Skin Rash
Symptoms of Shingles
Shingles, also known as herpes zoster, is a painful skin rash caused by the varicella-zoster virus, the same virus responsible for chickenpox. Shingles typically presents as a band of blisters that wrap around one side of the torso, although it can also appear on other parts of the body. The rash is often accompanied by pain, itching, and a burning sensation.
Causes of Shingles
Shingles occurs when the dormant varicella-zoster virus reactivates in the nerve cells, often due to a weakened immune system. Factors that can increase the risk of shingles include age (it is more common in people over 50), stress, and certain medical conditions or treatments that suppress the immune system.
Treatment Options for Shingles
Antiviral medications, such as acyclovir, valacyclovir, and famciclovir, can help shorten the duration of shingles and reduce the risk of complications. These medications are most effective when taken within 72 hours of the onset of symptoms. Pain relief can be achieved through over-the-counter pain relievers, prescription pain medications, or topical anesthetics. In some cases, a doctor may also prescribe corticosteroids to help reduce inflammation. (8)
