Polymorphic Light Eruption. Anyone else?

TheSunHasGotHisHatOnHipHipHipHooray · 27/05/2026 07:44

Does anyone else have this?

I was diagnosed as a young child and it hasn't really got any better!

I'm 51 now and I've never met anyone else with it or even anyone who has heard of it.
The NHS website describes it essentially as a mild irritation but it's debilitating. It also suggests it lessens over the summer as your skin becomes acclimatised. Mine doesn't.

It's not as bad as when I was a child but that ls probably because I'm an adult and avoid being outside altogether if I can help it.

The GP said it's basically an allergy to UV light, which seems to be held up by the fact that, when I was younger, I'd react even in nightclubs or at attractions with UV light. We were asked to leave places when I was a child because it looked to management like I had measles.

Exposure to sun causes a severe stinging nettle type rash on any exposed parts of my skin. Raised white lumps that group together to cause blotchy patches that are intensely itchy and surrounded by redness that are also incredibly painful to touch. I get it on my face and hands still but not as severely as I used to or on less exposed parts of my body. I don't get it so much on my face now but get what I assume is angioderma - swelling on my face that's really unattractive and causes large swollen sagging eye bags essentially that extend half way down my cheeks 😭 Antihistamines can take the edge off the itching but not really the pain and not the reaction in the first place.

I cover myself in factor 70 suncream but can still have reactions in strong sun (like this weekend has been).

Unfortunately, covering up is also hard because I don't tolerate heat very well and don't regulate my body temperature well so I overheat quickly and become ill through that. Using suncream can also have the same effect. It's a pain.

I'm also quite photosensitive generally. I wear sunglasses all the time outdoors unless the sky is dark and overcast with grey clouds. Even a cloudy sky can be too bright and painful!

It's never early occurred to me to go back to the GP about it. When I was a child (late 70s/early 80s) they said there was nothing for it but to stay out of the sun - which is hard to do! Avoiding the middy sun (11am - 5pm) doesn't really help because sun outside that also cases a reaction and being at work makes it difficult too.

It just makes normal life quite hard from light spring through to summer. I have a really shady garden (intentionally) and can sit out under the trees but no one else wants to constantly chase complete shade so it makes normal socialising with others tricky too.

I just wondered if anyone else on here has this or what your symptoms are like because, like I say, I've never met anyone else with it!

Ugh, the 'prickly heat' dismissal!

That is really irksome!

"Covering" doesn't need to be jeans and a T-shirt. You need loose but thick linen clothes.

Definitely go to the GP about it though. It's clearly impacting your quality of life.

Yeah, linen is my go-to clothing material. Drives me crazy with steaming and ironing but it keeps you cool without ending up in tight, inappropriate clothing on hot days.

A few years ago I had a private course of UV skin exposure therapy. It just delayed the onset for me into later in the summer but I know a few people who go for yearly seasonal UV exposure and they are symptom free for most of the season.

honeylulu · 27/05/2026 09:21

Yes I have this. It took ages to work out what it was. Doctor kept saying it must be an allergy to sun tan lotion etc. Then I met a dermalogist on holiday who recognised the rash (red, lumpy, itches like fury and if I scratch it, tiny blisters develop which are even itchier) and told me it was PLE. But when I mentioned it to the GP she said "oh yes, prickly heat". It definitely isn't prickly heat (which is from trapped sweat in concealed areas, PLE affects exposed skin.

I'm luckier than you in that I do gradually acclimatise to sunlight over the summer. But I'm on hols at the moment and it's the first strong sun my skin has seen this year. I've been really careful about covering up/using high factor sun screen (not least because I had a precancerous lump removed from my face last year) but I must have missed one ankle which is bright red, swollen, burning and itching - definitely not sunburn though.

Antihistamine cream helps a bit but if anyone else has found a remedy I am following with interest.

SleepingisanArt · 27/05/2026 09:18

I had it for a few years - it started suddenly and after 5 or 6 years stopped just as suddenly. (My immune system is hyperactive so reacts in odd ways to all sorts of things.) I wore factor 50 on all exposed parts of my body in the winter. In the summer I took double antihistamines and steroid tablets whilst wearing long sleeves and wide leg trousers (which I thought looked terrible because I'm short and the steroids meant I gained weight - better than the pain from the rash though). On holiday I'd sit on the beach in the shade wearing a maxi skirt and cotton shirt to stay cool and covered but my favourite place was in the pool (in a t-shirt) wearing a hat and sunglasses with the rest of my body submerged in the cool water.

OP go and get a referral- medicine has come on and there are things available to help ease your suffering.

My daughter's dermatologist said linen even thick still lets the rays through.

It does.

I know! But as a child in the 80s, I didn't have a whole lot of choice in what I wore!

roseymoira · 27/05/2026 09:14

I have it, not as sever as how yours sounds though. I’ve been prescribed oral steroids during a bad reaction, and I’m having phototherapy at the hospital for it. They give you a micro dose of UV during the winter months to acclimatise your skin. I think it would help you. I’d go back to your GP and ask for a dermatology referral. I had to wait about 5 months from referral to treatment.

I also have a UV umbrella that helps day to day

My daughter has it and I had it as a teenager and grew out of it. I'm 62 and sitting in the shade in Crete as I type with factor 50 on.
My daughter only really gets it abroad. She saw a dermatologist who gave her steroids and antihistamines which help a bit . She saw another dermatologist last week to discuss light therapy but was advised against as she doesn't get it in this country.(Scotland) And it's aging to the skin and increases your risk of skin cancers as you have to have 3 sessions a week for 3 months every year.
She suggested getting clothing that blocks uva and uvb. OP yours sounds quite severe so worth a referral.

WellFineThen · 27/05/2026 09:06

It's currently on both hands for me as a result of being in the "shade" on Saturday. The shade doesn't protect me because I think the UV rays go through or something. Have also had it on my ears and neck. It's embarrassing because I can't hide my hands and I'm so worried people will think I have some kind of communicable disease but can't do anything for it so just carry on.

TotallyKerplunked · 27/05/2026 09:03

Here too, mostly just my arms and chest (sometimes face) the itching drives me nuts and I've got scarring from scratching so much. I burnt a lot as a kid, I've always wondered if that caused it, parents never put suncream on me and were sun worshippers so shade, what shade?
Mines not an official diagnosis, I had a bad reaction in Spain a few years ago and that's what was suggested, Dr gave me a cream that was like smearing mashed potatoes up my arms 😝
Suncream doesn't seem to help much so I go for shade as much as possible.

Yes both my sons get this on their ears and down their neck, every year between March and July. It looks so sore, we use antihistamines and steroid cream to help and then it just disappears until next year.

Apparently, these a juvenile type that is more common in boys that particularly affects the ears! It is a juvenile form though so fingers crossed they'll grow out of it! 🤞🏻

Yes! As soon as the sun comes out. It honestly is so depressing. I can’t enjoy the sun at all. I still go on holidays and stuff but can’t stay outdoors. I’ve had some success with uv proof sleeves for my arms but they look ridiculous. I get it anywhere exposed to the sun (and sometimes even through clothes). The nettle sting rash is a very good description. I hadn’t thought about that before. The itching is unreal. Awake from 3am this morning with it. My doctor doesn’t seem to know what to do about it (though by the time I manage to get an appt the rash is normally gone). Aghhhhhh

Yes, I last went outside during 'daytime' on Sunday and was covered and wearing factor 70.

I still have itchy lumps now from it.

My face had gone down by the end of yesterday!

Definitely ask for a referral OP - there have been so many advances in treatment for auto immune and allergies since you were a child. Well worth trying if you are suffering this much.

witheringrowan · 27/05/2026 08:52

I have it too, horrible lumps all over my hands, chest and arms. Didn't use to be so bad, but it's getting worse in my 30s. Weirdly it's not too bad in UK sun, but anywhere south of the English Channel and I'm really struggling - maybe it's something to do with the light being more directly overhead? Never seen a GP about it, just smother myself in high UK sunscreen and wear long sleeves. But it would be lovely to be able to enjoy a beach holiday without worrying about my skin so much.

@TheSunHasGotHisHatOnHipHipHipHooray go back to your GP and ask for a referral to a dermatologist.

It's unreasonable that you should have to "just put up with it" and struggle on.

Thank you. I think I should. I've never done so becaise the doctors just said there was nothing they could do but I forget that that was 40+ years ago and things have changed!

I've been so used to just getting on with it that it seemed a bit daft to go back!

NT2018 · 27/05/2026 08:18

I have it too. Very bad on my chest and arms. I also have a skin reaction to very cold weather!

It’s a little less severe as I’ve aged but blights my life every year. I use massive factor suncream that blocks UVA and UVB, and a very thin prophylactic cover of steroid on any exposed skin although I generally cover up…I chase shade, even crossing roads multiple times. People think I’m nuts but I don’t care if it saves me from the pain.

Ha yes, I recognise crossing the road for shade. People think you're just being dramatic 🙄

I've been wary of adding extra layers of anything (inc cream) because I overheat easily. My body struggles with any change in temperature. Even putting a facial moisturiser on can cause me to over heat and sweat. Except in very cold (winter) temperatures. I don't use body lotion for the same reason. Tbh, I'm not even sure anymore if its a genuine sensory sensitivity or whether it was triggered by always being so hot as a child and my body just goes into overdrive.

There is a photo of me on the beach in France when I was about 10 which, to me, represents what life was like - my parents angled a large parasol on the beach to create a shelter I'm sitting under it wearing jeans, a long sleeve t shirt, with a bandana round my neck and in the background there are children on a hot sunny beach wearing swimwear and playing in the sea. I spent all ay sitting under the bloody parasol. I was so hot and miserable but the suncream at the time wasn't effective enough or was thick like toothpaste.

Lifepoint not related but apparently part of the same group of conditions. It's an over reaction of the immune system to UV radiation. Xeroderma Pigmentosum is horrific really. I can't even imagine that.

LathkillDale · 27/05/2026 08:40

I used to get it. One year, I had to have a steroid spray, as my eyelids and lips swelled up with it. I found being careful with what sunscreen I used made the big difference. I also never bare my shoulders, wear a sun hat and cover up more than other people generally.

I get brachial radial pruritus instead now. I’ve been offered gabapentin or pregabalin for it. This year, I am wearing long sleeves to see if I can avoid it this Autumn. I may be hot, but it’s more bearable than the itching!

I have a family member with it but it sounds less severe than yours OP. He can’t stay in the sun for long periods or the allergy erupts but he seems to get away with a little here and there. also not as bad as he’s aged a bit

Lifepoint · 27/05/2026 08:04

Is it related to Xeroderma Pigmentosum? I once had neighbours whose two little children had this, they called them moon children. They couldn’t cope with any daylight at all. The mum pushed them around in a covered black box, poor kids.

No.

Whenindoubthugitout · 27/05/2026 08:24

Weirdly, just on my feet, and it has gotten better as I have gotten older.

so incredibly painful! Can make walking very very uncomfortable.

i live in Scotland, so I’m in the main ok. I have to be careful on holiday, and spend most of my time in the shade, or with sexy socks on.

I can’t imagine how it must be to have it everywhere.
