What is this on DD'S foot? Picture included

[MegGriffin]

Suddenly appeared. She was itching it and looked down to see it. Any ideas? I have put antihistamine on it just in case. Thr white bit is slightly raised.

Maybe take her to the pharmacist? Is it sore?

Looks like an allergic reaction to something. I'd give her Piriton and monitor it closely.

Possibly ringworm?

It doesn't look like any ringworm that I've seen. It looks like a big hive.

has something bitten her?

Thank you. I have given her an antihistamine tablet and cream and will watch closely (she is 16).

Its not sore.

We can't see a bite mark.

It does look like a bite or allergic reaction to something causing a big hive. I hope the antihistamine works and it starts to clear up.

A bullseye rash can be from a tick bite. It's important to get her to the gp to investigate as Lyme disease can be quite debilitating if not treated. Hopefully it's just ringworm!

It looks like a big, solitary hive to me too. Maybe get it looked at by a HCP. And give Piriton. My son used to get hives, now outgrown it we think. He'd get them all over his arms and trunk.

This looks incredibly like Lyme Disease to me.
Please contact LDA on the above link for advice and send them a copy of the photo.
If it is Lyme Disease it is really important that a course of antibiotics is started immediately and continued for around a month.
If it is LD and this isn't done it can turn into a chronic, long term, debilitating illness which is extremely difficult to treat.
I have had LD for 8 years and know many other people in the same situation. I am now registered disabled.
Unfortunately most doctors in the U.K. Know little about LD and NHS tests are only 50% accurate. If a doctor suggests testing before treatment then do not accept this as it is wasting valuable treatment time. If they suggest testing after antibiotics then this is pointless as no antibodies will show up after treatment.
Even when GPS do prescribe antibiotics for LD they are usually for too short a time and too small a dose.
These are not dangerous antibiotics and are often given to teenagers long term for acne.
I am not scaremongering. My GP recently told me that he, or no other doctor in the practice, would diagnose me with LD as they didn't know anything about it.
It is extremely difficult to get adequate treatment on the NHS and this is where LDA may be able to help you.
I know of only two reputable private clinics in the UK which treat LD. One I have attended myself and they are not at all expensive.
If this is caught quickly enough it can be cured with no long term ill effects. I and so many other people I know are ill long term as we didn't get immediate treatment.
If you don't get any joy from LDA I can give you the clinic contact details so you can phone and ask for advice. It is in the north of England. The other I believe is very good, but more expensive, and is in the south.
Please PM me if you have any further questions at all.
I don't have any financial interest in either clinic but am just on of many LD sufferers trying to spread the message to prevent others suffering as we have done.

Thank you again for all your replies. The antihistamine seemed to work as it dissappeared within a few hours,very strange.

Hives.

Lyme and ringworm would not come up so quickly. It would be an unusual place to get a tick bite and not notice.

was she toasting her feet by the fire, or alternatively no socks and cold feet?

I often get great giant hives just like that because of extremes of temperature...often on my body, so for instance, out for a walk on a cold day, but you get up a head of steam and feel too hot, take off a layer and then bam! the itching starts, and once i start itching they spread

I took anti Hs every day for about three years as otherwise I'd break out everyday.....had a couple of years off as I ran out and the itching never flared up, but it's back again!

Meg I'm glad it has disappeared but please keep an eye on her just in case she seems unwell in the next few weeks. Hopefully it is not Lyme as the rash usually lasts longer but if you look at the link I sent you will see it looks lime a Lyme rash but really glad it doesn't seem to be.
Dipsy a large percentage of people do not notice they have been bitten by a tick, some of which are as small as a poppy seed. The bite is painless as they inject an anaesthetic before biting.
