Has she been allergy tested and not just the test the pediatrtion does but a blood test by an actual allergist that they send out and have done (takes about 2 wks to get back).
Does she ever get little pimple like things on her buttocks (can I say that here)?
I don't mean to be blunt but I'm not the sugar coating type, I have four kids and all had the same problem and everyone said get this cream and that one and give baths 2+ times a day, well nothing works very well and giving all the extra baths can exacerbate the condition and ironically enough my ped said it is impossible to be a food allergy they would be have other symptoms ie. respiratory, etc.
Well.....low and behold 3 of them tested positive for milk that gave no other signs except the lizard rash as I have dutifully named it, and I am not talking mild allergy. The testing scale has 5 levels 1 being trace and 5 being death.
Well all of mine test middle of the 3 level, yet one would think it wasn't that bad and even now my 4 year old will test completely negative if we avoid it for the 6 months between testing and the minute she has milk for even a day she gets her lizard skin back and looks like someone punched her in the nose b/c she gets horrible dark circles.
I have two who tested level 2 on peanut. My 10 yr old just came up positive in the last 6 mo. and she loves peanut butter and it only gives her a mild rash, my 1 yr old who also a low level 2 is just now able to be in the same room with someone eating peanuts or peanut butter. Quite a difference.
Moral of story everyones body reacts differently to different things, someones level 1 might act like a level 5 and someones level 4 might act like a level 1.
I would request a referral to a good allergist and have them do a blood test..not a skin test it is torture and not as accurate. My 4 year old tested neg on milk for skin test and blood test has come back with 98% accuracy. The library has good allergy books that explain the skin correlation and why it isn't always just "dry skin".
Sorry so long, but I get irritated when docs don't look at the bigger picture, they just say oh, it's a "virus" or it's no big deal. How do they know, are they that child or that child's parent. I always say you know your child best not your dr.
