Flushed face, heat, no other symptoms

[tatt]

Had a bit of a worry last night when my nut allergic teenager came home from a friend's house with a very red face and complaining of feeling hot. They assured me that hadn't eaten anything risky or drunk any alcohol and weren't having any breathing issues. They'd had an ice lolly before it started but have never reacted like this to cold things before. Dosed them with antihistamine anyway and let them stay up later than usual in case it was an allergy issue. Redness took a while to go down, not convinced the piriton made much difference.

They seem fine this morning, (ruling out something like a virus, they haven't had slapped cheek) so have gone to school. We try to handle this sort of thing as low-key as possible.

Anyone else had this sort of thing? Any ideas?

tatt hopefuly some one who knows will be along soon.

tatt, we've had dairy contamination reactions with ice lollies but it was a normal allergic reaction, though milder.
There are some very odd viruses about at the moment as teenage Dd (not allergic unlike Ds)had one last week (I think...)
dizziness, nausea, general malaise, feeling hot and cold but no fever,,,
Glad your teenager is feeling better

Could they be photo-sensitive? It produces a kind of sunburn like rash. I get this with most suncreams/perfumes/moisturisers in the summer. It always feels worse later in the evening if I've spent any time outside and occasionally I can get blisters. In fact, if any one has any suggestions for a suncream that is suitable, I'd be very glad to know as so far I have yet to find one even those that are designed for sun sensitive skins.
Even the briefest spell in the sun causes a reaction.

no definitely not photo sensitive. They normally adept very well to temperature changes and are not bothered by either high or low temperatures.

Obviously in someone else's home/car there is always a potential contamination problem but when they react its normally their throat that is affected.

nellymooe your gp might be able to prescribe something.

DS came home like that from someone's house. He is allergic to nut and seeds, but I am sure it was the dog that caused it. They had an old dog and everything including the car and the children's clothes seemed to smell of this dog.

They gave DS a lift home in the car and he was very flushed and "not right" He was later tested positive to cats, but he has never been tested for dog.
