daughter has bad eczema..need help pls.

my 3yr old has always had eczema but hers is really bad we have seen alot of doctors and such and they are no help they tell me that it should not hurt her or sting but i know it does cause when i had some yrs ago it does that but hers is much much worst.
she has it on under her hair and around ears on ears ,on face ,neck (the back of it )on shoulders just above the armpits,on tummy ,arms and hands,the front and back of her legs and thighs as well as her ankles.
i try the aveno stuff ..lotion and tub oatmeal for her it kinda works but she hates tubs cause they hurts her ... i feel alot of times like i am abusing my kid as i have to pin her down just to have a tub and put the lotion on afterwards she lays with me crying and shaking due to the pain a few times when it first happened and she hopped into a tub i thought she was having a seizure i am at the end of my rope her skins is covered with eczema and she straches it all the time i try to stop her but she also does it in her sleep and is raw and dripping in blood and wakes up cause that hurts hereven though i try to cover her arms and leg with big sicks that i have cut . can any one help me i have now moved to a very tiny town and the only way to get information is online i have been to so many sites reading but for the most part they are just selling stuff that cost alot and may not work .. ericka only eats a few things due to have several ear infections she also had along with her eczema what the doctors thought was ring worm on her tummy then said it was not. then was, then for sure was not ..since then her eczema has been super bad for the past 2 yrs it got a bit better before we moved but then my bf`s daughter had brought some sort of fungus to our house that the doctors thought was ring worm but then it was not since then her eczema has been really bad and nothing seems to be helping. i am not sure about doing those cleansing stuff as she is only 3. if anyone has some advice i would very much like it and would be so happy not to put her thought so much pain everyday ... and i find that doctors do not believe me when i have told them that everything hurts her .. water etc. and the creams and lotions burn her ... all they say is well ointment do not hurt. i then hae to them them that they do infact hurt i know this cause i have had it and my mom has eczema and has finailly found moducare pills that help hers but anyways. if anyone can her ericka can ya let me know thanks very much .
