Shingles (Herpes Zoster): Symptoms, Treatment, and When to Get Tested
When many people hear the word "herpes," their first impression is usually a sexually transmitted infection. However, shingles or herpes zoster is entirely distinct from herpes. While it is caused by a virus from the herpes family, shingles is not considered a sexually transmitted infection. Rather, shingles occur as the reactivation of the virus that causes chickenpox.
Chickenpox sufferers will carry the virus in their bodies for life even after recovering from the disease. The dormant virus can be present in the nerves, lying in wait to become active in the future when the immune system is weakened. As such, when the virus becomes active again, shingles can result from it.
The very first symptoms of shingles often include pain without any accompanying rash. Some individuals feel burning, tingling, itching, or sharp pains in certain areas of the body a few days before experiencing any rash. This is why shingles is initially thought to be just a muscle strain or back pain.
After several days, a red rash appears with small fluid-filled blisters. Unlike other types of rash, shingles generally occurs on one side of the body or face and runs along the route of a nerve. Later, the blisters break open, scab, and heal in about two to four weeks.
In addition to the rash, fever, headache, tiredness, chills, or body aches can occur. The rash can be extremely painful, while some people will continue feeling the pain long after the rash heals. This type of nerve pain, which is called postherpetic neuralgia, is the most common complication of shingles, especially in older adults.
Shingles may affect any person who has ever had chickenpox. But the risk increases with age. People older than 50, those with weakened immune systems, those receiving treatment for cancer, or people using medicines that weaken the immune system are at increased risk of developing shingles.
The earlier the treatment begins, the better it will work. The best results of antiviral medication, such as acyclovir, valacyclovir, and famciclovir, can be achieved if the drug is applied within 72 hours from the beginning of the rash. Antiviral medications cannot treat shingles; however, they can help to reduce the duration of the disease and lessen the severity of the problem.
Managing the symptoms and relieving the pain are very important while treating shingles. Managing the pain can be done with the help of prescribing prescription and non-prescription medications or using cool compresses or moisturizers according to the level of symptoms. Moreover, it is necessary to keep the rash clean and dry to prevent secondary infections.
Shingles are not contagious; however, the virus that appears in the blisters can be transferred to people who did not have chickenpox infection or vaccination before. In this way, this person will have chickenpox instead of shingles. All blisters should crust before people start contacting pregnant women, newborns, and people with weak immune systems.
For the majority of shingles patients, treatment usually results in recovery without any complications; however, in certain cases, prompt treatment becomes essential. Medical treatment will become necessary if the rash develops on your face, eyes, or ears; if the pain is intense; if the rash covers large areas of the body surface; and if you have a weakened immune system. The development of the disease may put your vision at risk if shingles appears in your eye.
It is also important to mention the preventative nature of shingles because vaccination can help avoid its occurrence completely. Most people above 50 years old, who experienced shingles before, are advised to be vaccinated against this condition to minimize its appearance.
To summarize, shingles is a preventable infection that can appear due to the activation of the chickenpox virus. Prompt treatment in case of shingles helps to alleviate your symptoms. Don't neglect your health if you notice a painful rash on your body that occurs after burning and tingling sensations.
