Shingles is a painful, blistering rash that follows one nerve on one side of the body. It is caused by the chickenpox virus waking up years later. Antiviral tablets help most when they are started within three days of the rash appearing.
The same eight facts on every condition comparison.
It is a reactivated virus.
The chickenpox virus can lie dormant in nerves and later reactivate.
It follows a nerve.
Inflammation follows a nerve band and causes a skin eruption.
Risk rises with weaker immunity.
Age and immune-lowering treatment increase risk, but younger people can get it.
Care has several parts.
Antivirals, pain control and checking for complications are each addressed.
It is inflammation of hair follicles.
It can be superficial or deeper.
It ranges in severity.
A small pustule can sit around a hair, while deeper infection can form a boil.
Not every case is infection.
Irritation after hair removal or reactions to products can look similar.
Scalp scarring needs attention.
Some follicle disorders can permanently damage hair.
Overview
Inflammation around hair follicles can produce itchy or sore bumps and pustules. Bacteria, yeast, irritation and occlusion are among the causes. This broad category includes Malassezia folliculitis; the cause determines treatment. Inflammation around hair follicles can produce itchy or sore bumps and pustules.

Truncal shingles A band around one side of the chest or back.
Facial and ocular shingles Forehead, scalp or around the eye.
Disseminated shingles Widespread; in weakened immunity.
Bacterial folliculitis Staph infection, the most common.
Hot-tub folliculitis From bacteria in poorly treated water.
Yeast folliculitis Uniform itchy bumps on chest and back.
Razor bumps (pseudofolliculitis) From hairs curling into skin.
Varicella-zoster virus remains dormant in sensory nerves after chickenpox. When it reactivates, it travels toward the skin and can cause pain and grouped blisters in a one-sided nerve distribution.
Infection, irritation or blockage can cause inflammation around a hair follicle. The response may produce a small tender bump or pustule around the follicular opening.
Shingles. Risk rises with age, particularly after age 50, but younger people can be affected.
Folliculitis. Folliculitis Any age There is no single typical starting-age range. Bumps can follow shaving, friction, sweating or hot-tub exposure. Recurrent or unexplained episodes deserve an assessment of the cause.
Shingles is caused by the chickenpox virus waking up years after it first infected you. The virus stays dormant in nerves and can reactivate later.
Folliculitis is inflammation of hair follicles, usually from bacteria, yeast or irritation.
Folliculitis describes a pattern of inflammation rather than one organism. Damaged or occluded follicles may become infected; shaving-related irritation can produce similar bumps without infection.
Most everyday folliculitis is not considered an inherited disorder. Skin conditions and individual susceptibility can influence risk.
Evidence labels come from each condition’s own treatment list.
The first step for shingles pain, and enough on their own for a milder episode. They work better taken regularly than only when the pain peaks. Shingles pain is nerve pain, so if these are not holding it, that is a reason to ring your doctor rather than to take more.
Dabbed on while the blisters are present, it cools the skin and takes the edge off the itching. A cool compress does much the same thing. Neither shortens the episode, and neither should be rubbed in, because breaking the blisters spreads virus and can leave scars.
An oatmeal soak can settle itching while the rash is blistering, in cool rather than hot water. It is comfort only. It does not change how long shingles lasts or whether nerve pain follows.
A thin layer of plain petroleum jelly on broken or crusting areas stops them drying and cracking, which lowers the risk of bacteria getting in. It has no effect on the virus itself. Use it under a loose, non-stick dressing rather than an adhesive one, which tears blisters when it comes off.
A 4 to 10 percent wash lathered on in the shower and left for a minute before rinsing, for the bacterial kind on the thighs, buttocks, chest and back. It lowers the bacteria on the skin without an antibiotic, which is why it also works as a maintenance measure for people who keep getting crops. It bleaches towels, sheets and colored clothing, so use white ones.
An antiseptic wash used two or three times a week over the affected area, and a good option for someone whose bumps keep coming back in the same place. It lowers the bacterial load on the skin rather than treating an established infection. Keep it away from the eyes and ears, and stop if it stings or dries the skin, since damaged skin is the problem you started with.
The standard first move for the yeast kind: itchy, uniform bumps on the chest, back and shoulders, often worse after a course of antibiotics. Use the shampoo as a body wash a few times a week and leave it on for several minutes before rinsing. It does nothing for bacterial folliculitis or razor bumps, and yeast folliculitis tends to come back, so many people keep using it once a week.
It is the obvious thing to reach for because the bumps itch, and it is usually the wrong one. Steroid cream quietens the itch for a few days while the infection in the follicles carries on underneath, and the rash that comes back is often more widespread. It also changes how things look, which makes the diagnosis harder afterward. Cool compresses and a medicated wash are the safer starting point.
A leave-on 2 percent lotion or pad on the beard, neck or bikini line, where the problem is hairs curling back into the skin rather than an infection. It keeps the follicle opening clear so fewer hairs get trapped, and it is used between shaves rather than on raw skin. It will not touch a bacterial or yeast folliculitis, and on already inflamed skin it stings and can make things worse.
It does have some activity against bacteria and yeast in the laboratory, which is why it appears in so many folliculitis remedies. There are almost no proper trials of it in folliculitis, and undiluted tea tree oil is a common cause of allergic contact dermatitis, which produces an itchy rash on top of the one you were treating. A benzoyl peroxide or antifungal wash is the better use of the same shower.
A numbing patch worn over the area for pain that carries on after the rash has healed. It goes only on intact skin, never on blisters or open areas. It helps some people a great deal and others hardly at all, so it is worth a proper trial before deciding.
A high-strength patch applied in a clinic for lasting nerve pain, with one treatment lasting up to three months. It burns while it is on, so the skin is numbed first. It is used after simpler options, and only once the skin has fully healed.
An antibiotic ointment used only if the crusts turn hot, swollen or start oozing pus, which means bacteria have moved in on top. It does nothing to the shingles virus. If the infection is spreading, antibiotic tablets are needed instead.
Clearing Staph from the nose. Some people carry Staphylococcus aureus in the nostrils or skin folds, which is one reason boils keep returning to the same person. A course of antibiotic ointment inside the nostrils, together with antiseptic washes and hot washing of towels and bedding, can reduce that. It is used for repeated boils rather than for a single episode, and it does not always hold, so household measures matter alongside it.
A lotion or solution for bacterial folliculitis spread over a wider area than an ointment can cover, such as the beard or the back. It is usually paired with a benzoyl peroxide wash, which both improves it and reduces resistance. It is not the answer if the same patch keeps returning, because that is a shaving, friction or occlusion problem rather than an antibiotic one.
The usual first choice for shingles: three doses a day for seven days. Started within 72 hours of the rash it shortens the episode and lowers the chance of lasting nerve pain. It does not clear the virus from the body, and it does much less once everything has crusted over.
An equally effective alternative to valacyclovir, taken three times a day for seven days. It is used when valacyclovir does not suit. The same 72-hour clock applies, and it is usually the more expensive option.
The oldest of the three antiviral tablets and the cheapest. It works just as well, but it has to be taken five times a day for seven days, which is harder to keep up. The dose is lowered if your kidneys are not working well.
Nerve pain medicines rather than ordinary painkillers. They are the main treatment for pain that carries on after the rash heals, and they are often started during the episode when pain is severe. The dose is built up slowly, and they can make you drowsy or unsteady at first.
A low dose of an old antidepressant, taken at night for nerve pain. It suits people whose shingles pain is keeping them awake. It takes a few weeks before you can judge it, and it is used carefully in older adults because of dry mouth, dizziness and confusion.
A short course of steroid tablets is sometimes added to antivirals for severe pain or when the facial nerve is involved. It can speed up rash healing and early pain a little. Studies have not shown that it prevents lasting nerve pain, and it is never given on its own for shingles.
The usual first antibiotic tablet for bacterial folliculitis that is deep, spreading or too widespread for a cream, and for boils with surrounding redness. A course is normally about seven days. It has no effect on yeast folliculitis or razor bumps, and if the same area keeps flaring after each course, the cause is still there rather than the antibiotic being wrong.
Used when resistant Staphylococcus aureus is likely or has been grown on a swab, which is the situation in which the first antibiotic did not work. This is the main reason for swabbing a spot before starting treatment. It is avoided in pregnancy and with some other medicines, so tell the prescriber everything you take.
An antifungal tablet, usually a short weekly course, for yeast folliculitis that is widespread or has not cleared with washes alone. It works faster and more completely than topical treatment on the chest and back. The yeast lives on everyone and comes back, so it is normally followed by an antifungal wash once a week to hold it.
A longer course is sometimes used for stubborn or recurring folliculitis, partly for the bacteria and partly because it calms inflammation. It is a second choice rather than a first one, since it can allow yeast folliculitis to take hold. It also causes sunburn easily, so it needs daily sunscreen on anything the sun reaches.
Two injections a few months apart, more than 90 percent effective at preventing shingles in adults 50 and over. It prevents rather than treats, so it is not used during an episode. It is still recommended once an episode has cleared, because having had shingles does not protect you from having it again.
Draining a boil. A boil that has come to a head is opened with a small blade under local anesthetic and the pus is let out, which relieves the pain almost immediately. It is often the whole treatment, with antibiotics only added if the redness is spreading. Done properly it heals with a much smaller mark than a squeezed boil, which is the argument for having it done rather than attempting it at home.
For folliculitis and razor bumps driven entirely by shaving, particularly in the beard and neck, reducing the hair removes the cause instead of treating the result. It usually takes six or more sessions and works best with a device suited to your skin tone, since the wrong one can burn or leave marks on deeper skin. It is worth considering after months of the same bumps rather than after one crop.
An episode runs two to four weeks, the pain sometimes longer. Most people get it once, though it can recur if the immune system is suppressed.
Many superficial cases settle with appropriate care, but repeated episodes need assessment for an ongoing contributor such as shaving, friction or infection. The course depends on the type; deeper inflammation can take longer to heal and may scar.
Postherpetic neuralgia
Nerve pain that carries on after the skin has healed, because the virus damaged the nerve it traveled down. It is the most common complication of shingles, and the risk climbs steeply with age. Starting antiviral tablets within 72 hours and controlling the pain properly from day one both lower the chance of it. It is treatable, so it is worth going back rather than waiting for it to fade.
Shingles in the eye
When the affected nerve serves the forehead and eye, blisters appear on the forehead, the eyelid or the tip and side of the nose, and the eye itself can be involved. It can cause lasting damage to sight. Blisters anywhere in this area are a same-day problem, and often need an eye specialist as well as antiviral tablets.
Shingles in the ear
Blisters in or around one ear, together with weakness on that side of the face, and sometimes a change in hearing, ringing or dizziness. It is uncommon. It needs urgent treatment, because the facial nerve recovers better the sooner antiviral tablets and steroids are started.
Boils and carbuncles
When the infection goes further down the follicle it becomes a boil: a tender, swollen lump that comes to a head over several days. Several joined together are called a carbuncle. Squeezing is what turns a surface bump into one of these, so warm compresses and leaving it alone are the right first move. Boils often need draining or oral antibiotics, and they can leave a scar.
Cellulitis
Sometimes the infection leaves the follicle and spreads into the surrounding skin. The signs are redness, swelling and warmth spreading outward from the spot rather than staying in it, sometimes red streaks running away from it, and often a fever. That is a same-day problem needing oral antibiotics, and it is more likely in people with diabetes or a weakened immune system.
Keloid scars
Deep folliculitis on the chest, shoulders, jawline and the back of the neck can heal into raised, thickened scars, and that risk is higher on deeper skin tones. At the nape there is a specific pattern, acne keloidalis nuchae, where the bumps become firm and permanent and the hair in that patch is lost. It responds far better to early treatment than to waiting, so firm bumps building at the back of the neck are a reason to be seen rather than to keep treating at home.
Seek prompt care when shingles is suspected because antivirals work best early. Eye or ear involvement, widespread blisters or weakened immunity needs urgent assessment.
Arrange assessment if the rash persists, keeps returning, is extensive or has not responded to treatment. A pustule swab may help distinguish bacteria and guide treatment.
Seek prompt medical care for fever, rapidly spreading redness or warmth, worsening pain, a large deep lump, or feeling unwell. Seek care earlier if your immune system is suppressed.
Bumps around the eye with eye pain, swelling, light sensitivity or vision change need prompt assessment. Do not apply body washes or skin medicines into the eye.
Not with shingles - nobody catches shingles from you. But the blister fluid can give chickenpox to someone who has never had chickenpox and never been vaccinated. Keep the rash covered, wash your hands, and stay away from newborns, pregnant people who are not immune, and anyone immunosuppressed until it crusts.
Possibly not. The evidence is strongest inside 72 hours, but treatment is often still given if new blisters are forming, if you are older, if the rash involves the face or eye, or if you are immunosuppressed. Being late is a reason to be seen today.
Nerve pain that continues after the rash heals, from damage to the nerve the virus traveled down. Much more common in older adults, and it can last months. It is treatable with different drugs from ordinary painkillers, so go back rather than waiting it out.
Generally yes. One episode does not protect you from another, and vaccination is recommended once an episode has cleared. Ask your doctor about timing.
The virus travels down a single sensory nerve, and each nerve supplies a strip of skin on one side. That is also why the rash stops abruptly at the midline - one of the clearest clues.
Yes, though most people do not. Recurrence is more likely if your immune system is suppressed. If it has happened more than once, ask whether anything underlying should be looked into.
Look for blackheads and whiteheads. Acne has them, folliculitis does not. Folliculitis bumps are all the same size, each sits at a hair, they itch more than they hurt, and they appear where you shave, sweat or rub - thighs, buttocks, beard, chest, back. Acne sits on the face, chest and upper back, has spots of different sizes, and is not itchy.
Mostly not in ordinary contact. The bacteria can pass through shared razors, towels, unwashed sports gear and close skin contact - avoid those while it is active. Yeast folliculitis and razor bumps are not caught.
Because the cause is still there - the shaving method, friction, damp clothes, or a yeast cause treated as bacterial. Some people also carry Staphylococcus aureus long term, which can be tested and treated.
Yes, but change how. A fresh single-blade or safety razor, with the grain, with gel, and no stretching the skin. Take days off while the skin is inflamed. For persistent razor bumps, laser hair reduction is a longer-term option.
Not on undiagnosed bumps. Steroid creams calm the itch for days while the infection carries on underneath, and the rash comes back more widespread. If itch is the main problem, a medicated wash and cool compresses are safer.
Superficial folliculitis heals without scarring, though flat dark marks take months to fade on deeper skin tones. Deep folliculitis and boils can scar, and firm raised bumps at the back of the neck can scar permanently - reasons to be seen early rather than keep treating at home.
