Hi my three year old has a rash. I noticed it this morning on the inside of her thigh and it spread while we were at the zoo.  It isnt blistered or raised...just red and splotchy.  The patches are very big and initially it looks like sunburn until you look closely and see that its actually small dots together.  you really notice the pepppering of small dots going down her calfs.  The rash is hot to touch where ever there is a large red patch.  She says it itches.  She played in her sandbox for the first time yesterday.  The rash seems to be everywhere the sand would have touched however last night at bath she didnt have it yet.  It developed over night I guess.  She has a skinned knee but there doesnt seem to be an infection near the wound.  She doesnt have a fever.  What is this?  Why is it hot?  Over the phone my ped. said to give benadryl and use cortizone and that it was likely contact dermatitis.  I didnt notice the heat coming off the rash until tonight after bathtime when their office was closed.
Hi... By what you quote it should be an urticaria or a simple skin allergy. You can use HY Chat Doctor.  Most important thing to be remembered is that it has a propensity to recur (called as second crop) within 10-14 days. If this happens, you can start using the same medicine, but I suggest you get the kid evaluated with your pediatrician. Regards -
