The term "herpes zoster" refers to a condition caused by varicella zoster virus, and varicella zoster virus causes varicella. After a person develops chickenpox, the virus is still dormant and is present in the nerve cells. Later, due to many different factors, the virus may reactivate and leave the nerve cells, which is the cause of herpes zoster or herpes zoster.
Reactivation usually occurs due to abnormal immune function. The presence of diseases such as age, rheumatoid arthritis, or the use of immunosuppressive drugs are risk factors.
Symptoms of shingles include early precursors or "time before the storm." Patients may develop flu-like symptoms, headaches, and may have low fever and chills.
Shortly thereafter, the patient will notice itching, burning, and uncomfortable feelings. This discomfort usually occurs in the chest or back, but can also occur in the abdomen, head, face, neck or arms or legs.
There may also be swelling of the lymph nodes near the uncomfortable area.
The next stage after the prodrosis is the period of activity when a rash occurs. The appearance of the rash is quite typical. It appears as a small area or a reddish, slightly raised bulge. Although the rash may occur in many locations as described above, herpes zoster only affects one side of the body. As the rash evolved, it became like a blister.
During this time, the pain may increase, and if it occurs on the upper back, it may cause pain to radiate to the scapula.
If a rash occurs on the forehead or face, the danger is eye development, which can lead to blindness.

During a period of time, the blisters open, ooze out, and then begin to crust. Although the healing process can take several weeks, some patients will leave scars.
The unfortunate problem is that if the patient enters the chronic phase, it is called post-herpetic neuralgia. This is a terrible complication that may last for years. The key symptom is persistent burns and stinging in areas where there is a rash. Because pain is chronic and persistent, it interferes with activities of daily living.
One fact is that herpes zoster can occur without producing a typical rash. However, there are other symptoms of burning.
There is a herpes zoster vaccine. It is a live vaccine, meaning it contains live viruses and should not be given to patients who use biopharmaceuticals. Although the vaccine has no effect on everyone, it is strongly recommended according to the following situation of the Centers for Disease Control and Prevention...
"Zostavax® for zosters is licensed for people 60 years of age and older to prevent herpes zoster in the elderly. The more severe the effect of herpes zoster, so all adults 60 years of age or older should get Herpes zoster vaccine."
