Hi everyone, its comforting to know that we're not the only ones dealing with this. My daughter is 9, let me start off by saying, shes sensitive to alot of things, sunlight, heat, cold, etc. but it's never been an actual allergy. For instance she can get a mosquito bite and it will swell up like she's been bit by a snake. about a week and a half ago, maybe 2 weeks, we got our christmas tree out of the storage room and before I put it up I wanted to clean the carpets so I used my new carpet cleaner and used the sample bissell cleaning solution that came with it, there was only enough to do a portion of my floors with that cleaner. So after everything dried and we got the tree up my daughter and son (like they always do) laid under the tree, smack dab on top of the freshly cleaned floor. That was around 3:30-4pm, around 10:00 she came to me with what looked like a mosquito bite, she was scratching like crazy. she got in the shower and by the time she had got out her back and legs were covered, and it wasn't just a rash, these were HUGE raised hives that went the length of her legs. Scared the crap out of me, so I gave her some benadryl and put her to bed with me so I could watch her, about 1 am I opened my eyes and looked at her and her face was covered, arms, almost everything. So I got her up and put her in a luke warm tub thinking something was still on her. This has gone on for this long, last week I took her to the doctor Monday and he put her on prednisone, after 3 doses there was no change, they seem to be the same if not worse so I took her back in Tuesday and he said to give her the full 5 days of steroids before panicking, well she was done with the steroids on saturday and she has broken out every night since then, tonight is the worst, its almost covering her back. I thought at first it was the carpet cleaning detergent, because it was new, I had never used that brand of cleaner before. But shouldn't it be out of her system by now, I went back over the area with plain water, I've vacuumed, etc. Something has to give, It seems to happen mostly at night when she's all covered up, although it did happen once at school while she was on the carpet, the teacher said once she got her up off the floor she started clearing up. And then once at walmart while she had a heavy jacket on, her arms were covered. I just dont get it, there's got to be something causing this all of a sudden, I would be more than happy to get rid of whatever it is if I just knew! If its my husband or my son, they're out, lol! Anyway, thanks for all the stories and suggestions, hopefully we will all feel better soon!
