Is it herpes, or something else?
If you have found something and gone straight to a search engine, start here. Most people who ask this question turn out not to have herpes — and either way, a page cannot tell you. What it can do is help you work out what you are probably looking at, and what to do next.
The honest version, first. Nobody can diagnose this from a description, a photograph, or a website — including us. Herpes is confirmed with a swab taken from a sore while it is still present, and that is done in person. If you have something now, the useful move is to be seen while it is there, because the test is most reliable in that window.
In the UK that is free. Search for your local sexual health clinic, or call NHS 111 for advice on where to go. It is quick, it is routine to them, and it is the fastest way to stop guessing.
What herpes usually looks like, plainly.
Not a checklist to diagnose yourself with. A description of the typical pattern, so you can see whether what you have resembles it at all.
- It often announces itself first. Many people notice tingling, itching, burning or a dull ache in one spot a day or two before anything is visible. That warning phase is called the prodrome.
- It tends to come in groups. Small blisters clustered together in one area, rather than a single isolated bump.
- The blisters break. They open into shallow, tender sores, then crust and heal — usually without leaving a scar.
- It is normally sore. Uncomfortable, stinging, sometimes painful to urinate if the sores are close by.
- A first episode can come with flu-like symptoms. Fever, aching, swollen glands, feeling generally unwell. First episodes tend to be the worst, and later ones are usually milder and shorter.
A single painless lump that has been there for weeks and never blistered does not fit this pattern well. Neither does a rash that is itchy but has never formed blisters or open sores.
What it is most often confused with.
These are the comparisons people search for most. Each one has a tell — but a tell is a clue, never a conclusion.
Ingrown hair or razor bump
The most common false alarm by a distance. Usually a single bump rather than a cluster, often with a dark dot or a visible hair at the centre, and it tends to follow shaving or waxing. It looks more like a spot than a blister, and there is no tingling beforehand.
Folliculitis
Inflamed hair follicles: several small spots, each one centred on a hair. It can look like a cluster at a glance, which is why it gets mistaken for herpes — but the spots sit on follicles, and the pattern follows where hair grows.
A spot or pimple
Raised, often with a white or yellow head, and it comes to a point rather than forming a thin-roofed blister. Usually one, usually not preceded by tingling, and it does not break into a shallow open sore.
Shingles
Confusing, because shingles is a herpes-family virus — herpes zoster, the chickenpox virus reactivating. It is a different condition from genital herpes. The tell is the shape: shingles follows a single nerve, so it appears as a band or stripe on one side of the body and does not cross the midline.
Thrush
Itching, soreness and a thick discharge, without blisters or ulcers. Thrush is a yeast overgrowth, and it is extremely common. The absence of blistering is the main thing separating it from a herpes episode.
Mouth ulcers
Aphthous ulcers — the ordinary kind — appear inside the mouth, on soft tissue like the inner cheek. Cold sores caused by HSV appear on or around the lip border, on the outside. Location does most of the work here.
Contact dermatitis or shaving rash
Diffuse redness and irritation across an area rather than defined blisters in a cluster, and it usually tracks a new product, fabric, or a recent shave. It itches more than it hurts.
Syphilis
Worth knowing because the tell runs the opposite way. The sore of early syphilis is typically single and painless, where a herpes sore is usually tender. Painless does not mean harmless — syphilis needs treating, so a painless sore is a reason to be seen, not a reason to relax.
Genital warts (HPV)
A different virus entirely. Warts are firm, flesh-coloured growths that persist and grow slowly. They are not blisters, they do not burst, and they are usually painless.
Something else entirely
Cysts, skin tags, molluscum, friction sores and irritation from tight clothing all show up in this list of worries. Genital skin is skin, and it does ordinary skin things.
"Is it still herpes if it doesn't itch?"
It can be. Itching is common but not required, and symptoms vary a great deal between people and between episodes. Some people have a textbook first episode and then years of almost nothing. Some have episodes so mild they are put down to friction or a spot. Some people carry the virus and never notice a symptom at all.
Which is the honest, slightly unsatisfying answer to most questions in this shape: the absence of one symptom does not rule it in or out. That is precisely why the test exists, and why guessing from a symptom list — including ours — is not a substitute for one.
Three steps, in order.
Be seen while it is there
A swab taken from an active sore is the most reliable test. If you have something right now, that window matters — do not wait for it to heal before booking.
Use the NHS for this part
Sexual health clinics do this every day, it is free, and it is confidential. Search for your local clinic or call NHS 111. This is the right route, and we will always say so.
Wait before you conclude anything
The internet is a poor place to spend the days before a test result. If it helps, read what herpes actually is — the facts are calmer than the reputation.
If the answer turns out to be yes, it is a smaller thing than you have been led to believe.
It is common, it is manageable, and the fear around it was largely manufactured within living memory. There is a steady way through, and it starts with an ordinary conversation rather than a crisis.
