About Shingles
Shingles, also known as herpes zoster, is caused by the reactivation of the varicella-zoster virus. The virus remains dormant in the nerve cells after a person has had chickenpox. When the immune system weakens, the virus can reactivate and cause shingles.
Non-modifiable risk factors are factors that cannot be changed or controlled. The non-modifiable risk factors for shingles include:
- Age: The risk of developing shingles increases with age, especially after the age of 50. People over the age of 80 have the highest risk.
- Previous infection: If you have had chickenpox in the past, you are at risk of developing shingles.
Modifiable risk factors are factors that can be influenced or changed. However, some potential modifiable risk factors may include:
- Weakened immune system: Certain health conditions like HIV, cancer, and receiving immunosuppressive medications can weaken the immune system and increase the risk of shingles.
- Long-term steroid use: Prolonged use of steroids, such as prednisone, can increase the risk of shingles.
It is important to note that these are general risk factors and individual cases may vary. Consult with a healthcare professional for personalized advice.
The most common early symptoms of shingles include:
- Pain: A constant dull, burning, or gnawing pain, or a sharp, stabbing pain that comes and goes.
- Rash: A skin rash that resembles a chickenpox rash but only affects certain areas.
- Blisters: Fluid-filled blisters that develop as part of the rash.
As shingles progresses or becomes more severe, other common symptoms may occur. These can include:
- Itching, tingling, or numbness of the skin.
- Fever.
- Fatigue.
- Headaches.
- Swelling.
In some cases, shingles can affect specific areas of the body. Common locations include the chest, abdomen, back, and around the waist. If the rash affects the face, symptoms usually appear on one side only, typically around one eye and the forehead. Eye symptoms such as pain, redness, and swelling can occur if the virus affects an ophthalmic nerve.
Remember to consult your doctor for an accurate diagnosis and appropriate treatment.
To diagnose shingles, doctors commonly perform the following examinations, tests, and procedures:
- Physical Exam: Doctors evaluate the appearance of the rash and blisters on your body.
- Medical History: Doctors ask questions about your medical history to understand your symptoms better.
- Tissue Sample: In some cases, doctors collect a sample of fluid from the blisters and send it to a lab to check for the presence of the virus.
- Blood Test: Doctors may conduct a blood test to look for antibodies, which can determine whether you have been exposed to the virus.
To determine the stage or severity of shingles, additional examinations, tests, and procedures may include:
- Skin or Fluid Sample: In rare instances, doctors may need to test a sample of your skin or fluid from the blisters. This involves collecting a sample using a sterile swab and sending it to a medical laboratory for confirmation.
- Endoscopy: If shingles is suspected in the throat, an endoscopy may be performed. This procedure involves inserting a thin tube with a camera into the throat to examine it in more detail.
- Polymerase Chain Reaction (PCR) Test: PCR tests detect the virus from samples taken from the lesion. These tests provide rapid and accurate results and are particularly helpful in diagnosing atypical cases.
Remember, it's important to consult with your healthcare professional for personalized advice and guidance regarding examinations, tests, and procedures for diagnosing and determining the stage or severity of shingles.
The goals of treatment for shingles are to:
- Relieve pain: Medications such as antiviral drugs, analgesics (pain relievers), and topical creams containing lidocaine can help alleviate pain associated with shingles lesions. Antiviral medications like acyclovir, famciclovir, and valacyclovir are commonly prescribed to reduce the severity of symptoms and shorten the duration of the infection.
- Prevent complications: Antiviral medications taken within 3 days of rash appearance can reduce the risk of developing long-term nerve pain or other complications like postherpetic neuralgia (PHN).
- Speed up healing: Antiviral medications help in faster healing of shingles lesions by suppressing the replication of the varicella-zoster virus (VZV) responsible for the infection.
- Manage symptoms: Therapeutic procedures such as thermotherapy, including fire acupuncture and moxibustion, have shown potential benefits in relieving pain and improving quality of life for patients with shingles and postherpetic neuralgia.
It's important to note that treatment options may vary depending on individual cases, and it is recommended to consult with a healthcare professional for personalized care. They can provide guidance on medication types, therapies, and health behavior changes specific to your situation.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
