3 year old daughter with hives, confused about it

Hello. Earlier this summer, my daughter broke out in this really weird looking rash that kept disappearing and reappering in diffrent spots. i had no idea what it was, so I took her to the ER. They told me it was hives and just to give her benadryl. Well although benadryl and creams and oat baths work great, she's getting them almost everyday!!! And i feel so bad for her cause she looks miserable and it makes her cry. I told her doctor at the time and he told me it wasnt anything big. Well now im in the process of finding her a new doctor, can I demand they give her tests to see whats causing the hives, or is there even a test?? I really wish I could find whats causing them, they started out of nowhere and I spent days after her first attack seeing if i used anything new, like soaps or perfume or cleaners.. and I hadn't bought anything diffrent then what i've always used. I know sometimes their's no known cause for them. She also has suffered from asthma since she was a newborn and gets lots and lots of runny noses and watery eyes. We have no pets either. SO again my question is, is there tests that can be done to test for whats causing her hives. I'm just wanting to know so i know what to ask when i call within the next few days to find her another doctor. AND any information I should know about hives would be great. THANK YOU

My Dr.now is pretty sure I have Impetago.Darn!! I'll get a antibiotic cream for it this morning as the pharmacy was closed last note.

hi,
the prednisone also worked for my 9yr old, but she was having a reaction to amoxicillin..my oldest used to get hives all the time when she was little..and only in the summer time...we could not figure out anything...same as you we checked soaps etc...i still thinking it was something outside from her playing in the grass or in the air causing it...it almost sounds enviromental with the runny nose etc..hope you find some answers..its very hard when they are little..good luck..ems

Hello. Thankyou so very much for the replies. I've forgot to mention that my daughter has been on singulair for about 2 years now. I'm wondering if their's any other allergy medicine for young children thru RX that maybe she can take daily that would better. I always feel terrible when I give her benadryl cause it makes her sleepy and I dont like to make my kids sleepy thru medicines. She's also been on prednisone before also a few times, I beleive it worked well but she only took it for a few days if I remember right. I know I just took prednisone a few months ago for my sinuses, but have no idea what it does LOL. Well thank you again.

Hello~Kitty,
I can sympathize with you for having a child with hives. My youngest daughter used to get them constantly and we just got so we gave her the bennedryl and followed it up with a big glass of cola (the caffein helps counteract the drowsiness). On the advice of our pediatrician we took her to an allergist who had her tested in his office. She had a complete back scratch test with really eye opening results. She reacted to almost all of the 80 allergens tested. Some of them we later learned were only the cause of contact dermatitis or hives and others were life threatening. Some of them were hilarious! She can eat potatoes and french fries but she can't peel them! (We told her it was just so she could get out of helping with dinner!) She received the testing and started on her injections when she was 6 and the results took time but were well worth it. She had about 8 yrs of shots and eventually she got so she didn't need prednisone to survive August. She was on Claritin when she was three, but only because she was so tall and big for her age. The loratidine seems to work pretty well for her but lately (she's 23) it appears to be causing headaches. Now she has a job and a home of her own and teases me that our old cure is still the best. She takes her benendry with Mountain Dew now, but it's still caffein and sleepy pills. Wish I could be more helpful.
