DS has a big pink/red patch on back

[LadyOfWaffle]

running from top to bottom, like he has laid on something but he hasn't. He was ok a little while ago - just did a poo explosion so I gave him a quick bath and have noticed in when he got out. No little dots or anything - just dark pink. Like sunburn, but it's definatly not. Any ideas? out of hours gp..? thanks

Was he laying down on his back on the bath? Or have you been holding him? It may be the heat.

How long has he had it?

seems to be about 15 mins. it's wonky, same colour as when you have pink bits on legs from warm bath, but totally wrong shape & bath was very cool. Not from holding... ill look for camera lead and take pic ...

Are you using a new soap? if so, can you give him another bath but now just with plain water, no soap?

Is the patch itchy? raised? spreading? if it is not, I would just leave it to subside.

pics 2 & 3.... no soap at all

Do you have allergies in the family? (asthma, eczema?) If so, was there any new or non regular ingredient in his food?

Is the patch itchy?

I wouldn't worry too much, but will keep an eye on whatever he had to eat today in case the reaction is repeated in the future.

If the patch is spreading ring NHS direct, but I don't think they will ask you to go to A&E unless breathing was compromised. DS gets that with certain foods and a dose of piriton usually sorts him up.

NO allergies... seems to have calmed down - maybe it was the heat? I will keep an eye on it though. He was itching it a tiny bit but maybe that because I was poking and prodding . Not dry/flaky.
Thanks
