What are these black dots / marks on my daughter’s hands

Any doctors reading who might be able to put my mind at rest about these black marks / dots that have appeared on my 13 year old daughter’s hands over the past few days? We have a GP appointment (Bupa video call) booked tomorrow but I’m worried that she maybe needs to be seen more urgently? Anyone ever seen anything like this before? Thanks so much

She just said a boy accidentally splattered her hands with silver nitrate in Biology - she hadn’t thought of it before because the liquid was clear, but that makes sense as it darkens over time! Thank you all for (probably) solving the mystery!!

I’m really quite relieved now having got to the end of the thread!

I feel really relieved as well!

I’d totally be spiralling, but this seems like it must be the right answer.

Oh gosh, that sounds stressful for them, I’m glad it got sorted in time. Would it be itchy though?

It's not scabies.

Has she been gripping something very hard?

Dumbells/barbell/gymnastics or cycling?

I wondered this, as I had similar ish looking bruising from gripping oars to row.

Christwosheds · 22/11/2025 22:27

I see probably silver nitrate , glad you have worked it out !

Are you absolutely sure it couldn’t be pen?

I thought that, she could have been sticking a pen into her palms.

However, glad to know you've found the solutiion.

Could it be poison ivy, have a look at the black dots from that or a similar allergic reaction? Maybe try an antihistamine

Poison ivy doesn’t exist in the UK.

vickylou78 · 22/11/2025 22:43

Yes definitely silver nitrate when you put on as a verruca treatment it makes skin go black

lessglittermoremud · 22/11/2025 22:54

If it’s silver nitrate you maybe able to get it to fade using vinegar or lemon juice

FluentOP · 22/11/2025 21:46

I am not a doctor but I am wondering if it could be sepsis. If so, it would be a medical emergency. If it’s definitely not pen, perhaps get it checked out.

Bingo!

Thanks so much all! I’ll update you after we see the GP tomorrow - see what they say!

I would think the GP will have no idea, unless you tell them it's silver nitrate 😀

Any chance she has been doing experiments or something similair in her science lessons / perhaps touched a substance left behind on the tables / sides from another lesson whilst in the science room etc? The dots looks almost like silver nitrate specks. That stuff really does stain and will not wash out but doesn’t explain the itching… (have got the stuff on my hands myself as work in a vets and we use silver nitrate to stem a bleeding dogs nail if cut too short) totally random but just what it reminds me of!

This is what I thought of straight away. I use it at work and never know I've got any on my hands until hours/days later when it 'develops'. It's routinely used in school science lessons so she could have come across quite easily.

Surely you won't see a GP on a Sunday will you?

shuggles · 22/11/2025 23:23

@Onelife2024 She just said a boy accidentally splattered her hands with silver nitrate

That was my first thought when I saw the photograph.

asparagusffern · 22/11/2025 23:46

My son had ITP, dangerously low platelets as a toddler. It started as a few dark pin prick spots and spread over the next few days. He had no other symptoms of illness but had a cold the previous week which the doctors thought had triggered it. He was hospitalised for a week and required a blood transfusion.

GlomOfNit · 23/11/2025 00:01

OP, has she had a virus with a sore throat recently? Hand Foot and Mouth gives you blisters on your hands and feet soles, and after they've flattened they can look a bit like that. Just a thought, though perhaps they're too dark.

They look like flat blood blisters!

GlomOfNit · 23/11/2025 00:07

oh god sorry, RTFT! Grin So glad it's something non-traumatic, OP!

Surely if a pharmacist has said you should go to A&E, then you should go to A&E. They are highly trained medically.

I wouldn't risk A&E on a Saturday night unless the child was obviously distressed or in pain.

Louise303 · 23/11/2025 00:28

Could it be something people in school are doing over 40 years but remember both boys and girls puncturing skin and using ink. Or something in colour enhancing shampoo that has stained open skin.

JFDIYOLO · 23/11/2025 00:46

Try nail varnish remover on a cotton bud on a small mark. See if it removes it. That will tell you if it's biro ink.

Check out her clothes, schoolbag, books - any similar marks on them?

Please don’t advocate against a health professional. You do what you want to do but imagine if you gave that advice and a child died

CuddlyPug · 23/11/2025 00:52

Silver nitrate definitely stains. I dyed my eyebrows once with a product with silver nitrate and I skipped gloves! My eyebrows looked good but the blackened nails were less chic. Nothing takes silver nitrate stains off fingernails. You just have to grow them out. It took a few days of scrubbing to get off my skin - there was no magic bullet that I found.

They are not highly trained medically. They are highly trained pharmacists but even with a prescribing qualification, they are very different.

Onelife2024 · 22/11/2025 21:15

Ok, thank you - worth a go!

Maybe but I’ve had poison ivy rashes many times and they never looked like this!
