It
might begin as a strange burning sensation or tingling on your skin — easy to
brush off, at first. But within days, that discomfort could turn into a painful,
blistering rash. This is shingles,
a condition far more serious than many realize, and one that can affect your
body long after the rash has faded.
Whether
you’re looking to protect yourself or support someone going through it, here’s
what you need to know about this often misunderstood illness — including its
symptoms, risk factors, and the preventative steps that can make all the
difference.
What
Exactly Is Shingles?
Shingles,
medically known as herpes
zoster, is caused by the varicella-zoster
virus — the same virus responsible for chickenpox. If you had
chickenpox as a child, that virus didn’t disappear. Instead, it went dormant,
hiding out in your nerve tissue, possibly for decades.
But under the right conditions —
especially when your immune system is weakened — the virus can reactivate as
shingles, bringing intense nerve pain and a rash that often wraps around one
side of the torso.

Who’s
Most at Risk?
Not
everyone who had chickenpox will develop shingles, but certain factors raise
the risk significantly. These include:
- Adults over the age of 50
- People with weakened immune systems, such as
those with cancer, HIV, or undergoing chemotherapy
- Individuals recovering from illness or trauma
- People under chronic stress
- Organ transplant recipients
Even healthy individuals can develop
shingles, but those with compromised immunity or heightened stress are
particularly vulnerable.
Early
Symptoms to Watch For
Before
the rash even appears, shingles often announces itself with subtle signs,
including:
- Fatigue
- Fever
and chills
- Sensitivity
to light
- Headache
- Stomach
discomfort
Within a few days, more visible symptoms
appear:
- A
tingling, burning, or itching sensation on one side of the body
- Redness
in a localized skin area
- Raised,
fluid-filled blisters that eventually crust over
- Pain
— which can range from mild to severe and persist even after the rash
fades
Shingles
Isn’t Always Skin-Deep: Know the Complications
The
painful rash is only one part of the story. In some cases, shingles can lead to
serious health issues, including:
- Postherpetic neuralgia — long-lasting nerve pain in the
affected area
- Bacterial skin infections from open blisters
- Vision problems or eye damage (if
shingles affects the face)
- In
rare cases, neurological
complications, including brain or spinal cord inflammation
Prompt treatment is essential to reduce
the risk of these outcomes.
Is
There a Way to Prevent Shingles?
Yes
— and it’s recommended for many adults. The Shingrix vaccine (recombinant zoster vaccine or RZV) has
been shown to dramatically reduce both the risk of developing shingles and its
potential complications.
Healthcare providers typically recommend
vaccination for:
- Adults
50 years and older
- Adults
19+ with compromised immune systems
Ask your doctor whether you’re a good
candidate for the vaccine — especially if you’ve had chickenpox or aren’t sure
about your past exposure.

Treatment:
What to Do If You Get Shingles
While
there’s no cure that eliminates the virus entirely, early treatment can help control symptoms and shorten
the duration of illness.
Antiviral medications are most effective when started within
72 hours of rash onset:
- Acyclovir
- Famciclovir
- Valacyclovir
These drugs can reduce the intensity of
symptoms and help prevent complications like nerve pain. Additional treatments
may include:
- Pain relievers, such as ibuprofen or paracetamol
- Anti-inflammatory medications (like
prednisone) for facial shingles
- Antibiotics, if a secondary infection develops
Note:
Never self-diagnose or treat shingles without medical advice.
Is
Shingles Contagious?
Shingles
itself isn’t contagious — but the virus
is.
If someone with an active shingles
outbreak has close contact with a person who’s never had chickenpox (or hasn’t
been vaccinated for it), that person can catch
the virus and develop chickenpox, not shingles.
To prevent spreading the virus:
- Keep
the rash covered
- Avoid physical contact with pregnant women, infants, or
immunocompromised individuals
- Wash your hands frequently
Final
Thought: Know the Signs, Protect Your Health
Shingles
is often underestimated — until someone experiences it firsthand. The pain,
fatigue, and possible complications can disrupt daily life, especially for
older adults or those already managing other health concerns.
But you’re not powerless. With early
awareness, timely medical care, and preventive measures like vaccination, you
can reduce your risk and protect your quality of life.
If you’ve had chickenpox, it’s worth
knowing what’s hiding in your nerves — and how to stop it from reactivating
when you least expect it.
