Chapter Five · Lichen sclerosus
A condition that is common, treatable, and routinely takes years to name — partly because of where on the body it is.
Start with a phone call. Your doctor’s office has a triage line and a nurse will talk it through with you. They are good at this, they do it all day, and it costs nothing. You ring the main number and ask for the triage nurse. There is no charge and you do not need an appointment.
If it feels more serious than that, go to urgent care. You will usually be seen faster than at a hospital.
If it feels life-threatening — chest pain, trouble breathing, confusion, no urine at all for a day — call 911 or go to the emergency room. Do not wait until you are sure. Take the more cautious road.
Rather listen?
Takes about 8 minutes, read aloud. It is the same words as the page below, so nothing is missing if you would rather read. Download it to keep on your phone — it will play with no signal, in a waiting room or a car.
It is a long-term skin condition, and it is treatable. Left alone it scars.
Treated, most people do well. The whole difficulty is in it being recognised.
→ where this is explained: What it is
The delay is not your fault and it is not unusual. Several years between the
first symptom and the right name is the ordinary experience, not the unlucky one.
→ where this is explained: Why it takes years
If the pain has outlived the visible disease, there is a reason for that. The
nervous system can stay switched on after the skin has settled. That is a recognised thing
with its own treatment.
→ where this is explained: When pain outlives the disease
Tick the ones that apply. The bar below shows how much they add up to.
What we would do, as a friend rather than as your doctor. This is our opinion and we stand behind it. It is not medical advice and we are not examining you.
It is not a one-time reading. If you start feeling worse while you are deciding, move up a level. Nobody has ever been criticised for turning up and being sent home. A false alarm is the best possible outcome here.
If none of these apply, the rest of this chapter is worth your time. Take it slowly; there is no clock on it.
An inflammatory skin condition. The skin becomes thin, pale and fragile, and over time can scar and change shape. It most often affects the genital skin, in women and in men, and it can appear elsewhere. It is not an infection and it is not caught from anyone.
Grade B It is understood as autoimmune in character — the immune system acting against the body’s own tissue — with several mechanisms described in the research rather than one: an immune attack on a protein in the skin, a scar-building signal that stays switched on, oxidative wear the body cannot keep up with, and an inherited susceptibility.
Three reasons, and none of them is about the person who has it.
Where it is. The area is not examined routinely, and it is not always easy to raise. If a doctor does not look, nothing is seen.
It is mistaken for other things. Thrush, irritation, dryness after the menopause, or simply “sensitive skin”. Treatments for those do not help, and not helping is itself information that often does not get acted on.
The visit is short. The source guide behind this chapter has its own section called The Seven-Minute Problem, written before this book existed. A condition that needs an examination, a history and an unhurried conversation does not fit the appointment it is given.
Some people find the pain continues after the skin looks treated and settled. This is recognised. Long-lasting pain can change how the nervous system handles pain signals, so that the alarm keeps sounding after the original cause has been dealt with.
Grade B It matters practically, because it means more of the same skin treatment is not the answer, and because the treatments that do help are different ones. It also means the pain is real and is not evidence that you are exaggerating — a thing many people with this are told, or come to believe.
Other autoimmune conditions occur more often in people who have this one — thyroid disease, coeliac disease, type 1 diabetes, alopecia areata, lupus, Sjögren’s syndrome and psoriasis among them. That is worth knowing in both directions: it is a reason to mention this condition when another autoimmune problem is being investigated, and a reason to mention the others here.
Usually by looking, by someone who knows what they are looking at. A biopsy is used where the appearance is not typical, or where something needs to be excluded. There is no blood test that settles it.
Because it can scar and because there is a small increase in skin cancer risk in the affected area, being under review matters as much as the first treatment does.
“Would you look, please?” It is a reasonable request and it is the step that most often does not happen.
“I have been treated for thrush or irritation several times and it has not helped. What else could this be?”
“If this is lichen sclerosus, what is the treatment, and how will we know it is working?”
“How often should this be reviewed, and what should I watch for between reviews?”
