Shingles are red rashes which occur mostly in older adults or people with weak immunity. There is no particular medical treatment to cure it. Therefore you must know how to prevent it from occurring.
- Shingles are red rashes which occur mostly in older adults.
- Caused by reactivation of the varicella-zoster virus, it occurs in 3 stages.
- You may experience burning sensations and aches in the initial stages.
- It cannot be treated medically, only its duration can be reduced.
Shingles occurs in older adults and people with weak immune systems as a result of stress, injury, certain medicines, or other reasons. The common symptoms of shingles are pain and rash on one side of the body, the left or right.
Shingles or herpes zoster is caused by reactivation of the varicella-zoster virus in the nerve roots. Varicella-zoster virus is a type of herpes virus that causes chickenpox. In most people the virus remains inactive in nerve roots following chickenpox. But in some it flares up (the virus becomes active again) to cause shingles. Anyone who has chickenpox (mild or severe infection) can get shingles. If your immune system is weakened, reactivation of the virus that causes shingles can occur. Some of the factors that can weaken your immune system include aging, injury, stress, certain medicines and illness.
Shingles develops in stages.
Prodromal stage: Early symptoms in prodromal stage (before the rash appears) in people with shingles are
- The initial stage is marked with symptoms such as pain, burning sensation, numbing or tingling sensations near the location of the affected nerve. This is often experienced days before a rash occurs. Affected areas of the body can include the chest or back, head, face, neck region or limbs.
- Flu-like symptoms such as chills, stomach ache, or diarrhea, may start before or along with the rash. But the flu-like symptoms usually occur without a fever.
- Swelling and tenderness of the lymph nodes.
Active stage: Rash and blisters appear in the active stage of shingles. The rash generally appears in a small area and tends to be in patches. They can appear anywhere in the body but a characteristic of shingles is that it appears on only one side of the body, either left or right. The rashes can range from being mild to extreme with blisters being filled with colorless fluid which gradually becomes opaque in few days. It may take a fortnight to four weeks for the rash to heal. An occurrence of rash around the eyes (herpes zoster ophthalmicus), should be attended immediately with medical help as the risk of one’s eyesight getting affected is high. The pain experienced in shingles can mimic ‘piercing needles’, which is accompanied with a rash in this stage.
Postherpetic neuralgia or chronic pain stage: Postherpetic neuralgia is a common complication of shingles. It can last from a month to years.
Symptoms of postherpetic neuralgia are
- Aching, burning, stabbing pain in the area of shingles rash in the past.
- Persistent pain for months or years.
- Extreme sensitivity to touch.
Pain of postherpetic neuralgia most often involves the forehead or chest. The pain can make daily activities like eating, sleeping difficult. Chronic and severe pain of shingles can lead to depression.
Tests and Diagnosis
Shingles is a clinical diagnosis and a doctor can usually identify shingles by its appearance as an area of rash around the left or right side of your body. If the diagnosis is not clear lab tests, most commonly herpes tests, on cells taken from a blister will be needed.
If the diagnosis is clear your doctor may not wait to perform tests before starting treatment with antiviral medicines. Early treatment with antiviral medicines has been noted to shorten the length of the illness and prevent complications such as postherpetic neuralgia.
Shingles are not cured by any particular medical treatment instead treatment only helps in lessening the duration of this condition and also inhibiting any complications.
