Shingles is caused by reactivation of the chicken pox virus, which lies dormant in anyone who has had chicken pox. It begins with pain or tingling in an area of skin on one side of your body or face, followed by a rash of small, fluid-filled blisters. You may also have a headache and fever.

01 · Know
What is Shingles?
Shingles is caused by reactivation of the chicken pox virus, which lies dormant in anyone who has had chicken pox. It begins with pain or tingling in an area of skin on one side of your body or face, followed by a rash of small, fluid-filled blisters. You may also have a headache and fever.
The blisters scab over and heal within a few weeks, but the area may remain painful for months afterward — a condition called postherpetic neuralgia. Shingles is more common in later life. Stress, ill health, or sunlight can trigger an attack. You cannot catch shingles from someone else, but you can transmit the chicken pox virus to anyone who has not had it.
02 · Understand
Clinical context
See your doctor first
Arrange to see your doctor to confirm shingles. Antiviral medication is most effective when started within 72 hours of the rash appearing — early treatment reduces severity, duration, and the risk of postherpetic neuralgia.
03 · Act
Seek further medical advice if:
- 1Blisters become pus-filled or spread beyond the original area.
- 2You develop severe headaches or vomiting.
- 3Pain is not controlled by analgesics, or pain persists long after the blisters have healed.
- 4You have a weakened immune system — you may need closer monitoring and stronger antiviral treatment.
04 · Prevent & manage
Practical steps
Start antiviral treatment early
Self-care alone is not sufficient for shingles. See a doctor as soon as the rash appears — prescription antiviral medication started within 72 hours can significantly reduce the severity and duration of the illness and lower the risk of long-term nerve pain.
- 1Rest.Rest as much as you can to speed your recovery. Shingles places significant demands on the immune system.
- 2Stay hydrated.Drink plenty of fluids while you have a fever.
- 3Relieve pain.Take acetaminophen, aspirin, or ibuprofen to relieve pain, headache, and fever. A cold compress — a cloth soaked in ice-cold water — may also help relieve skin pain and tingling.
- 4Soothe skin with baths.If you have blisters on your body, take lukewarm baths 2–3 times a day. Add baking soda (4 tablespoons to a two-thirds-full bath) or use an oatmeal product to soothe itchy, blistered skin.
- 5Keep blisters clean.Gently wash any blisters on your face with soap and water. Do not burst blisters — this increases infection risk and delays healing.
- 6Avoid contact with vulnerable people.Until all blisters are dry, avoid skin-to-skin contact with anyone who has not had chicken pox — particularly pregnant women, newborns, and immunocompromised individuals.
Practical technique
Practical technique — soothing baths for shingles
Reducing itch and discomfort from blisters
Lukewarm baths with soothing additives can significantly reduce the discomfort of shingles blisters. Use them 2–3 times daily while blisters are active.
- Baking soda bath: Add approximately 4 tablespoons (about one cup) of baking soda to a bath two-thirds full of lukewarm water. Soak for 10–15 minutes.
- Oatmeal bath: Add oatmeal oil or colloidal oatmeal to the bath, or use oatmeal lotion instead of soap when washing.
- Cold compress: Between baths, apply a cloth soaked in ice-cold water to the most painful areas for temporary pain and tingling relief.
Pat skin dry very gently after bathing — do not rub. Rubbing can irritate blisters and cause them to break. Apply loose, soft clothing afterward.

BarnMD Bottom Line
Shingles can be painful, but most people recover fully. The shingles vaccine (Shingrix) is available for adults aged 50 and older and significantly reduces the risk of an attack.
Ask your doctor about the shingles vaccine — it is the most effective way to prevent shingles and its complications.
