Shingles: Early Symptoms, Treatment Timing and How to Prevent It
Written by Cherlie Joseph, MSN, FNP-BC · Medically reviewed by Naurah Gaspard, DNP, FNP-C, FNP-BC · Updated November 2026
Shingles usually starts with burning, tingling or pain on one side of the body, followed a few days later by a band of red, blistering rash. Antiviral medicine like valacyclovir works best when started as soon as the rash appears, ideally within 3 days. The Shingrix vaccine, two doses for adults 50 and older, is the best way to prevent it.

What causes shingles and who gets it
Shingles is caused by the same virus as chickenpox. After chickenpox, the virus stays asleep in nerve roots for decades. Later in life it can wake up and travel along one nerve to the skin, which is why the rash follows a band or strip on one side of the body.
About 1 in 3 people in the US will get shingles in their lifetime, according to the CDC, and more than 99% of Americans born before 1980 had chickenpox. Risk rises after age 50 and with a weakened immune system, such as from cancer treatment, steroids or other immune-suppressing medicines. Stress and illness can be triggers, but many people have no obvious reason.
Early symptoms and the stages of the rash
| Stage | What you may notice |
|---|---|
| 1 to 5 days before the rash | Burning, tingling, itching or sharp pain in one area; sometimes headache, tiredness or feeling feverish |
| Days 1 to 5 of the rash | Red patches, then clusters of small fluid-filled blisters, in a band on one side |
| About days 7 to 10 | Blisters break and crust over |
| 2 to 4 weeks | Scabs heal; skin may stay discolored for a while |
The most common spots are the chest, back and waist, wrapping around one side. The face, around one eye or the forehead is also common and needs prompt care. Before the rash shows up, shingles pain is often mistaken for a pulled muscle, a kidney problem or even heart pain.

Antiviral medicines, valacyclovir (Valtrex), acyclovir or famciclovir, slow the virus. Started early, ideally within 72 hours of the rash appearing, they can shorten the illness and ease pain. They are usually taken for about a week. Some people still benefit when they start later, especially if new blisters are still forming or the eye is involved, so it is worth being seen even if you are past day 3.
Other things that help:
- Pain relief: acetaminophen or ibuprofen as the label directs. Shingles pain can be severe; tell your provider if over-the-counter options are not enough.
- Cool, wet compresses and calamine lotion for itching and burning.
- Loose, soft clothing over the rash.
- Keep the rash clean and covered; avoid antibiotic ointments unless a provider recommends them.
Postherpetic neuralgia is nerve pain that lasts for months after the rash heals. It is the most common complication and is more likely with age. Medicines such as gabapentin or certain antidepressants, and lidocaine patches, can help.
Is shingles contagious?
You cannot catch shingles from someone. But fluid from shingles blisters can spread the virus to someone who has never had chickenpox or the chickenpox vaccine, and they would get chickenpox, not shingles. Shingles is not contagious before blisters appear or after all blisters have crusted over.
- Keep the rash covered and wash your hands often.
- Avoid contact with pregnant people who have not had chickenpox, newborns and anyone with a weakened immune system until your blisters crust over.
- Many people can work if the rash is covered and they feel well enough; ask your provider about your situation.
Preventing shingles with Shingrix
The CDC recommends two doses of Shingrix for adults 50 and older, and for adults 19 and older with a weakened immune system. The second dose is given 2 to 6 months after the first. In clinical trials, Shingrix was more than 90% effective at preventing shingles.
- You should get Shingrix even if you have had shingles before, or had the older Zostavax vaccine.
- Sore arm, tiredness and muscle aches for a day or two are common.
- Most insurance plans cover it, and many Florida pharmacies give it without an appointment.
Get in-person care or call 911 if you have:
- A rash on your forehead, around your eye or on the tip of your nose, or eye pain, redness or vision changes
- Confusion, a severe headache, stiff neck or weakness on one side of your face
- A rash that spreads beyond one area or covers large parts of your body
- Fever with spreading redness, pus or red streaks
- Chest pain without a rash (do not assume it is shingles; call 911)
Frequently asked questions
What does the start of shingles feel like?
Most people feel burning, tingling, itching or a sharp pain in one area on one side of the body for 1 to 5 days before any rash appears. Then red patches and blisters show up in a band.
How long does shingles last?
The rash usually blisters, crusts and heals over 2 to 4 weeks. Some people, especially older adults, have nerve pain that lasts for months afterward.
Can you get shingles twice?
Yes. Most people get shingles once, but it can come back. That is why the CDC recommends Shingrix even after you have had shingles.
