Question: 15 mo. old with disappearing rash?
|turbog73 - Sun Dec 28, 2008 12:44 pm||
My 15 month old has a rash on his tummy and back that "appears" in the evening and is gone by morning. We have ruled out an allergic reation to laundry soap, and have not changed his diet at all. We have given him benadryl(sp?) and the bumps are gone by morning. They look like tiny spider bites-red bumps in no particular pattern, but they are itchy (I assume, since they get even more red from him rubbing them). He otherwise acts healthy and happy. What is going on?

While you've done very good detective work, it's more difficult to isolate the source of dermatologic allergic rash in small children, mainly because they can't tell us much. The fact that the rash appears at a certain time of day suggests contact with or ingestion of something late in the day which is causing this. The cause can sometimes be pretty obscure. If it continues it would probably be best to bring it to the attention of his pediatrician, although you still may realize what's different at this time (and the difference can also arise in the course of doing or ingesting something normal, as allergies don't always announce themselves on first exposure -- it's just that when they do it's usually a dramatic and obvious connection, whereas cumulative allergic exposure usually is more sneaky).
These also could well actually be spider bites. Stranger things have happened. Not as likely as an allergic reaction to something, but certainly possible. Keep the Benadryl handy, but if this continues, it's going to require the services of a medical professional to inventory all the possible causes.
Best of luck to you and please do follow up with us here -- and update us if you learn anything new.
